A Central Asian state bordering China, Kyrgyzstan became independent with the collapse of the Soviet Union in 1991.

It has some oil and gas and a developing gold mining sector, but relies on imports for most of its energy needs.
Resentment at widespread poverty and ethnic divisions between north and south have spilled over into violence, and the country's first two post-Soviet presidents were swept from power by popular discontent.
Settled by Kyrgyz tribes from southern Siberia in the 17th century, the area was ruled by various regional powers before coming under Russian, and then Soviet, rule.
Most of its six million people are Turkic-speaking Muslims.
In 2014 Kyrgyzstan shut a US military base which had supplied US troops in Afghanistan with personnel and cargo since 2001. Russia retains a military airbase in the country.
Population 5.4 million
Area 199,900 sq km (77,182 sq miles)
Major languages Kyrgyz, Russian
Major religions Islam, Christianity
Life expectancy 64 years (men), 72 years (women)

President: Almazbek Atambayev
Almazbek Atambayev, a businessman and former prime minister, won more than 60% of votes in the October 2011 presidential election, trouncing his nationalist rivals.
His inauguration marked the first peaceful transfer of presidential power in Kyrgyzstan's post-Communist history.
Under pro-Russian Mr Atambayev, Kyrgyzstan joined the Russian-dominated Eurasian Customs Union.
He also refused to extend the lease on the US air base at Manas - a logistics hub for the Afghan conflict - in 2012, soon after accepting a loan from Russia; the base closed in 2014.
1685 - Kyrgyz people settle in the area that is now Kyrgyzstan; area conquered by the Oirats, a Mongol people, after centuries of Turkic rule.
1758 - Oirats defeated by Chinese Manchus and Kyrgyz become nominal subjects of Chinese empire.
Early 19th century - Kyrgyz come under the jurisdiction of the Uzbek khanate of Kokand, to the west.
1876 - Russian forces incorporate what is now Kyrgyzstan into the Russian empire.
1991 - Kyrgyzstan acquires its present name, and declares independence. Askar Akayev is president.
2005 - Mass protests force President Akayev from office in the Tulip Revolution.
2010 - Opposition protests sweep President Kurmanbek Bakiyev from power.


Shares of Nomura have jumped by as much as 9% following reports it plans to cut jobs and reduce the size of its European equity business.

The BBC understands that its equity research, underwriting and derivatives businesses will be closed.
Around 500 to 600 jobs in the US and Europe are expected to be lost in the downsizing, according to Reuters.
A separate report by the Nikkei newspaper said the potential cuts could be up to 1,000 jobs.
Nomura said it would announce its full strategic plan on April 27 along with its annual results.
"We are taking decisive action to refine the services we offer to our clients," Nomura chief operating officer Tetsu Ozaki said in a statement.
"This exercise will deliver significant efficiencies and cost savings for Nomura, refocusing the firm's activities and reallocating resources towards its areas of expertise and most profitable business lines."
Japan's largest brokerage has struggled to make profits from its overseas businesses and is said to be looking to reduce costs.
Global investment banks have been scaling back their businesses as market volatility eats into revenues.
Banks such as Credit Suisse, RBS and HSBC have cut jobs and either shut or sold non-core business units in recent years.
Nomura had looked to bolster its brand overseas by purchasing Lehman Brothers' European and Asian operations after the US investment bank went under in 2008.
However, the integration proved to be costly and Nomura undertook a major cost-cutting plan in 2011 to stem further losses.
Nomura's third quarter net income fell by 49% from a year earlier to 35.4bn Japanese yen ($327m; Â£230m) because of market volatility.
It has since undergone a senior management reshuffle, with its chief operating officer and chief financial officer being replaced last month.


Billionaire US President-elect Donald Trump has said he is not obliged to cut ties to his business empire when he takes office on 20 January.

A Democratic senator is tabling a resolution calling on him to liquidate his assets to prove he does not intend to profit from the office of president.
There is no legal requirement to liquidate assets but past US presidents have set aside their business dealings.
Mr Trump also disowned far right activists who hailed his election win.
"Alt-right" activists could be seen making Nazi salutes at a conference in Washington DC over the weekend, where a speaker enjoined them to "Hail Trump".
Mr Trump, who has flown to Florida for the Thanksgiving holiday on Thursday, is still assembling his White House team. One of America's top generals, David Petraeus, has told the BBC he would be willing to serve under him.
"In theory I could run my business perfectly and then run the country perfectly," he told the New York Times in an interview.
"I'd assumed that you'd have to set up some type of trust or whatever and you don't."
However, he added that he would "like to do something" to separate his two areas of responsibility.
Democratic Senator Ben Cardin would like a more formal separation. He plans to introduce a resolution next week calling on the president-elect to adopt blind trusts or take equivalent measures to ensure that he complies with the constitution over potential conflicts of interest.
The property tycoon is said to be currently worth $3.7bn (Â£3bn) by Forbes magazine, with more than 500 different enterprises in his business empire.
One example of a possible conflict of interest is the newly opened Trump International Hotel in Washington DC, the BBC's David Willis reports.
Mr Trump already stands to profit from an influx of visitors in the weeks leading up to his inauguration.
Since the hotel sits on land leased from the federal government, when Mr Trump assumes office, he becomes, effectively, both landlord and tenant overnight, our correspondent notes.
Eyebrows were also raised when Ivanka Trump joined in a phone conversation her father had last week with the Argentine President, Mauricio Macri.
The Argentine government later denied reports that Donald Trump had asked Mr Macri to approve a building project by one of his companies in Buenos Aires.
Apart from condemning the far right, he defended hiring Steve Bannon, the former CEO of radical conservative news site Breitbart, as his strategist.
"Breitbart is just a publication," Mr Trump told the famously liberal newspaper. "They cover stories like you cover stories."
"If I thought he was a racist or alt-right or any of the things, the terms we could use, I wouldn't even think about hiring him", the president-elect added.
He also argued that:
And he accepted there was some "connectivity" between human activity and climate change.


Debris from the grounding of the drilling rig Transocean Winner has been found at Dalmore beach on Lewis.

Between 30 and 40 pieces, mostly metal parts, have been found to have broken off the structure, which was blown on to rocks in bad weather on 8 August.
The debris ranges from laptop size to a 1.5 tonne thruster.
The rig has since been towed to a new temporary anchorage off Lewis, but an exclusion zone remains in place at Dalmore, near Carloway.
Divers have been recovering the broken parts by hand.
However, a crane is to be used to recover the thruster, which detached from a leg of Transocean Winner during the grounding.
Other debris could be washed ashore during autumn and winter storms.
The Transocean Winner was being towed from Norway to Malta from where it was to be moved to a yard in Turkey to be broken up.
A tow line between the rig and a tug broke during stormy weather and the structure ran aground.
All broken pieces which have been recovered so far have been stored temporarily at Carloway.
Deputy Secretary of State's Representative Maritime Salvage and Intervention, Colin Mulvana, said: "The divers are working very hard to make sure that they are picking up all the bits found on site.
"But there may well be previously undetected debris that may appear following bad weather."
Mr Mulvana said the rig's owners, Transocean, would arrange future surveys of the area for debris.
He added: "Our advice remains the same as it has from the start - please stay off the beach while the diving operation continues and while the temporary exclusion zone (TEZ) is still in place.
"We know that surfers and walkers, including those with dogs, use Dalmore Bay and will continue to use it after the diving operation is over and the TEZ has been lifted.
"We'd just like them to be aware of the possibility of debris washing up over the next few months. Just keep an eye out, particularly after stormy weather for anything unusual."
Anyone finding parts from the rig should contact the coastguard, he said.
Transocean Winner has been secured to eight anchors in Broad Bay on the east side of Lewis.
The Maritime and Coastguard Agency said there was no sign of pollution and monitoring continued. Divers and remotely operated vehicles have been checking the structure for damage.


Dyw penderfyniad Theresa May i gynnig £1bn ychwanegol i Ogledd Iwerddon am gefnogaeth y DUP i'w llywodraeth yn ddim mwy na "phrynu pleidleisiau", yn ôl prif weinidog Cymru.

Mae'r DUP wedi cytuno i roi cefnogaeth i lywodraeth Mrs May yn San Steffan, fydd yn golygu pleidleisio gyda'r Ceidwadwyr ar achlysuron pwysig fel y gyllideb ac araith y Frenhines.
Er hynny, nid oes clymblaid ffurfiol rhwng y ddwy blaid.
Ddydd Llun, dywedodd Carwyn Jones bod y cytundeb yn "gwanhau'r DU" ac yn "lladd y syniad o gyllid teg i genhedloedd a rhanbarthau'r DU".
Fel arfer, mae'r setliad ariannol rhwng gwledydd y DU yn ddibynnol ar Fformiwla Barnett.
Ond mae ffynonellau wedi awgrymu wrth y BBC na fydd yr arian ychwanegol i Ogledd Iwerddon yn effeithio ar y fformiwla, gan mai ar brosiectau penodol y bydd yn cael ei wario.
Dywedodd Mr Jones: "Arian yw hwn mewn envelope i'r DUP, dyw hwn ddim byd i wneud â sicrhau llywodraeth gadarn i'r Deyrnas Unedig, ac wrth gwrs cael gwared â'r rheolau sy'n llywodraethu'r ffordd mae arian yn cael ei ddosbarthu dros y Deyrnas Unedig.
"Mwy o arian felly i Ogledd Iwerddon, dim ceiniog i Gymru na'r Alban, a pham dyle cleifion, er enghraifft, yng Ngogledd Iwerddon gael mwy o arian y pen, [a] bod yn fwy gwerthfawr i Theresa May na chleifion yng Nghymru?
"Dyna'r cwestiwn mae'n rhaid i Lywodraeth y DU ateb."
Ychwanegodd: "Ni wastad wedi cael arian i addysg ac i iechyd drwy Fformiwla Barnett, nawr mae Gogledd Iwerddon yn cael mwy o arian y tu fas i Fformiwla Barnett.
"Pam? I brynu pleidleisiau, nid rhyw egwyddor mawr, rhywbeth mor isel â hynny."
Yn gynharach, dywedodd Mr Jones ei fod wedi siarad ag Ysgrifennydd Cymru, Alun Cairns.
"Fel llais Cymru yn y cabinet, mae ganddo [Mr Cairns] ddyletsrwydd i frwydro'n erbyn y fargen hon a sicrhau arian ychwanegol i'n gwlad," meddai.
Mynnodd Mr Cairns fodd bynnag nad oedd y setliad rhwng y Ceidwadwyr a'r DUP gyfystyr â "phrynu pleidleisiau", ac nad oedd yn golygu o reidrwydd y byddai rhagor o arian yn dod i Gymru.
"Y gwir yw bod Cymru nawr yn cael £120 am bob £100 sy'n cael ei wario yn Lloegr... mae'n setliad cryf a theg," meddai ar raglen Post Prynhawn BBC Radio Cymru.
Ychwanegodd y bydd Cymru'n elwa o fuddsoddiadau gwahanol gan gynnwys y bargeinion dinesig i Gaerdydd ac Abertawe, cynllun i dyfu economi gogledd Cymru, a chamau fel diddymu'r tollau ar Bont Hafren.
"Mae [Carwyn Jones] yn gwybod bod setliad cryf ofnadwy gennym ni. Mae e'n ceisio gwthio'r ddadl o danariannu Cymru ers blynyddoedd, ond y gwir yw o fewn chwe mis i fod yn Downing Street fe wnaeth Theresa May gytuno i'r pecyn ariannol newydd."
Fe ddywedodd Plaid Cymru y dylai Cymru gael mwy o gyllid yn sgil y fargen.
"Os yw'r adroddiadau bod y DUP wedi selio cynnydd o £1bn mewn gwariant cyhoeddus yng Ngogledd Iwerddon yn cael eu gwireddu, yna dylai Cymru gael tua £1.7bn yn ôl cyfran ein poblogaeth," meddai Liz Saville-Roberts.
Dywedodd y byddai'n "hwb sylweddol i economi Cymru".
Aeth y Ceidwadwyr i chwilio am gefnogaeth wedi iddyn nhw fethu ennill mwyafrif yn yr etholiad ddechrau'r mis.
Mae 10 AS y DUP yn rhoi mwyafrif ymarferol o saith i'r llywodraeth, gan nad ydy Sinn Fein yn cymryd eu seddi yn San Steffan a dydy'r Llefarydd a'i ddirprwyon ddim yn cael pleidleisio.


Scientists are a step closer to solving the mystery of one of the great animal migrations.

Each autumn, eels leave European rivers to travel across the Atlantic Ocean to breed for a single time, then die.
Tagging studies show that the fish swim more than 3,000 miles (4,800 km) to the Sargasso Sea.
But, rather than one mass spawning in the spring - an idea held for a century - their arrival is staggered, UK researchers say.
"Eel migration is a rather romantic tale," said lead researcher David Righton, head of the Centre for Environment, Fisheries and Aquaculture Science (CEFAS) in Lowestoft.
"Eels only spawn once in their lifetime and then they die, so they're making this final journey of their life, towards the Sargasso Sea, to meet their life's goals, if you like.
"And so the fact that we've got a little bit of insight into that - but we've also got some new questions about how eels tackle that really fundamental problem of meeting that life goal - is really, really fascinating."
The life cycle of the eel has long puzzled scientists.
Even the Greek philosopher Aristotle pondered the question of where eels came from, deciding that they sprang up spontaneously from the mud.
Almost 100 years ago, it was discovered that their destination was the Sargasso Sea, in the western Atlantic near the Bahamas.
This led to the assumption that all eels took the shortest and quickest route across the ocean from freshwater rivers and streams.
"What we've found is that [some] eels actually take a more convoluted route to the Sargasso Sea,"  said Dr Righton.
"We propose that eels probably have a strategy that enables some eels to arrive in a very short period of time but others to take a longer, more meandering journey and perhaps arrive up to a year later and spawn in the subsequent seasons."
Eels arrive around the European coast as tiny glass eels, having drifted across the Atlantic for two or three years from the Sargasso Sea.
In the autumn, the mature eels - growing up to one metre long - leave European rivers and fresh water and disappear into the ocean, never to be seen again.
Until now, it has been very difficult to study their migration across the ocean.
Now scientists have a "roadmap" of the migration of eels towards the Sargasso Sea, based on tracking hundreds of eels from five locations in Europe.
Data from the five-year study shows that most eels begin their migration between August and December.
Yet, the migratory timing and speeds of eels vary so that only the fastest arrive in time for peak spawning in the Sargasso Sea in the spring while others arrive much later, only to breed the following season.
The European eel is classed as critically endangered.
The fish face many threats on their migration, including damage from hydropower turbines, disease and parasites, exploitation and trade, habitat loss, pollutants, and predation.
A management plan is in place within Europe to try to boost eel numbers.
The new information about the rate of migration and their migratory strategy will help to improve that knowledge base, say the researchers.
The research is published in the journal, Science Advances.

Mae corff sy'n cynrychioli busnesau yn galw am adolygiad o'r drefn trethi busnes yng Nghymru.

Yn ôl Ffederasiwn y Busnesau Bach, mae angen system sydd ddim yn rhoi "sioc" i fusnesau bob tro mae'r cyfraddau'n cael eu hailasesu.
Ar hyn o bryd, mae hynny'n digwydd bob pum mlynedd.
Yn ôl y ffederasiwn, mae'r system bresennol yn achosi problemau, yn enwedig mewn ardaloedd gwledig.
Yn siarad gyda rhaglen Newyddion 9, dywedodd Josh Miles o Ffederasiwn y Busnesau Bach:
"Rydym ni'n credu fel yr FSB bod angen i Lywodraeth Cymru gynnal adolygiad o'r drefn i gyd i sicrhau ffordd o godi arian oddi ar fusnesau bach sydd ddim yn achos sioc bob pum mlynedd.
"Yn enwedig mewn ardaloedd gwledig, mae'r system bresennol yn achosi llawer o broblemau."
Un gwraig fusnes sy'n poeni am effaith ailasesu chyfraddau busnes yw Sian Fox, perchennog Foxy's Deli ym Mhenarth. Dywedodd y byddai unrhyw gynnydd yn effeithio ar ei chwmni.
"Mae unrhyw gost ychwanegol yn mynd i effeithio ar fusnes bach mewn rhyw ffordd - falle prisiau, falle cyflog y staff, torri oriau," meddai.
"I fusnesau bach mewn tref ym Mhenarth, dyle fod un pris (yn dibynnu ar) faint o staff sydd ganddoch chi, faint o turnover, rhywbeth fel 'na."
Dywedodd Llywodraeth Cymru: "Corff annibynnol, Asiantaeth y Swyddfa Brisio, sy'n gyfrifol am gynnal prosesau ailbrisio - mae'r rhain yn ymarferiadau mawr sy'n digwydd yn rheolaidd ar draws Cymru a Lloegr.
"Er bod y rhan fwyaf o fusnesau Cymru wedi gweld lleihad yn eu hardrethi busnes yn dilyn yr ailbrisiad diwethaf, mae rhai busnesau a rhai ardaloedd yng Nghymru wedi cael eu heffeithio mewn modd anghymesur.
"Dyna pam yr ydyn ni wedi cyhoeddi gwerth £20m o gymorth ychwanegol i fusnesau bach. Bydd hwn yn cael ei ariannu'n llawn gan Lywodraeth Cymru ac mae'n ychwanegol at ein cynllun Cymorth Ardrethi Busnesau Bach yn 2017-18, sy'n werth £100m.
"Yn sgil y cymorth ariannol hwn, bydd mwy na thri chwarter yr holl drethdalwyr yn cael help i dalu eu biliau.
"Rydyn ni wrthi'n edrych ar ffyrdd o wella'r cynllun Cymorth Ardrethi Busnesau  Bach ar gyfer 2018, pan fydd cynllun parhaol yn cael ei gyflwyno yng Nghymru. Fel rhan o'r broses hon, fe fyddwn ni'n ystyried yr holl adborth a dderbyniwyd gan y gymuned fusnes."


Relegation-threatened Nottingham Forest may have Matt Mills and Armand Traore back to face high-flying Reading.

Both defenders missed Monday's defeat at Cardiff, centre-back Mills suffering with a quad problem, while full-back Traore is nursing an ankle knock.
Reading manager Jaap Stam will wait to make a fitness decision on centre-back Paul McShane (hamstring).
Joey van den Berg (hamstring) remains out of contention for the Royals, who start the day in third place.
Reading, six points behind second-placed Newcastle United, must win to keep alive their automatic promotion hopes alive, while Forest start the day just a point clear of trouble.
They are a place above Blackburn Rovers, who face Wolves at Molineux, and two points behind 20th-placed Birmingham City, who do not play until Sunday, when Harry Redknapp takes charge of his first game against Aston Villa
Reading manager Jaap Stam told BBC Radio Berkshire:
"The opponents we're facing now, they're desperate to do well against us. That goes for Forest and for Wigan next week.
"At home, Forest are going to want to get a result, we know that and we need a result as well.
"So, it's going to be an interesting game and a very sharp game as well as they need to give everything to get that result.
"But I like playing in these games as it ensures everyone needs to work very hard and everyone is willing to do that."


A man has been found dead with serious stab wounds at a tram stop in Birmingham, police have said.

He was found collapsed at Benson Road tram stop, in Winson Green, and pronounced dead at the scene, British Transport Police (BTP) said.
It is not known whether the man, in his 50s, was stabbed on the platform approach or injured elsewhere.
Police, who were made aware of the incident at about 16:50 BST, have started a murder investigation.
Det Ch Insp Tony Fitzpatrick, leading the investigation with West Midlands Police, said: "We're still trying to establish exactly how the man came to receive his injuries."
"The incident occurred around rush hour and I'm certain they would have been people around who can help us find out exactly what happened."


Two of Northamptonshire's most senior police officers are to be investigated over "potential gross misconduct".

Assistant Chief Constable Andy Frost and Deputy Chief Constable Martin Jelley face claims their conduct in relation to an "internal professional standards matter" was inappropriate.
The Independent Police Complaints Commission (IPCC) is to lead the investigation.
Force Chief Constable Adrian Lee said he was aware of the investigation.
The watchdog will seek to establish whether Mr Frost's involvement in an investigation by the force's professional standards department was appropriate.
Mr Jelley, who is poised to leave Northamptonshire to become the new Chief Constable of Warwickshire Police, will be investigated "in relation to the delay in the referral of Mr Frost's conduct to the IPCC".
Chief constable Mr Lee said he was aware of the investigation, to be led by IPCC commissioner James Dipple-Johnstone, into the two officers and would "fully co-operate".
"As the Chief Constable for Northamptonshire I am the appropriate authority for conduct matters relating to DCC Jelley and ACC Frost," he said.
"As DCC Jelley moves to become the Chief Constable of Warwickshire Police the appropriate authority for his investigation will move to become the responsibility of [Warwickshire] Police and Crime Commissioner Ron Ball."


MPs are debating legislation to introduce five-year fixed term parliaments, part of a series of constitutional changes planned by the coalition government.

The Conservative-Liberal Democrat coalition government wants to set in stone the date of the next general election - which has previously been up to the prime minister of the day to decide. Under their proposals the next general election will be held on 7 May 2015.
Criticism of the current system tends to centre on the fact it gives an advantage to the prime minister of the day, who can choose to call an election at the most advantageous time for him or her as long as it is within five years of the previous election. It also means there is a period of uncertainty, before an election is called, which some say damages the conduct of politics.  A recent example was the feverish speculation that Gordon Brown intended to call a snap election in 2007 to take advantage of a poll surge shortly after succeeding Tony Blair as prime minister. In the end the poll lead was cut and he did not call an election until two and a half years later.
Some are worried that knowing the date a long time in advance will lead to longer election campaigns, a lack of flexibility and the possibility of a "lame duck" government limping on longer than it should. There is also the possibility that a government might still find a way of triggering an election when it wanted one by engineering a vote of no confidence and deliberately trying to lose it.
A commitment to a fixed-term parliament was part of the coalition deal between the Conservatives and the Liberal Democrats. The Lib Dems pledged to introduce them in their manifesto - but they wanted a four-year fixed term. The Labour manifesto also said it would introduce fixed term parliaments, but did not say how long they would be. Fixed term parliaments were not in the Conservatives' 2010 manifesto but David Cameron said in 2009 that his party would "seriously consider the option of fixed-term parliaments when there's a majority government".
Deputy PM Nick Clegg argued that five years was "going with the grain of some of the founding texts of our unwritten constitution" - referring specifically to legislation which set the maximum limit at five years. He also said it followed "the precedent set by the immediate outgoing government" and he said it would "give any government of whatever complexion enough time to govern and deliver a programme of change and reform". But the proposal could prove controversial. Constitutional experts told a committee of MPs examining the Fixed Term Parliaments Bill that four years would be better. Other UK elections to the devolved Scotland, Wales and Northern Ireland governments are four-yearly and there might be an argument to have them held on the same day as general elections.
Yes, there are two ways this could happen.  An early election would follow if no party or combination of parties could command the confidence of the House of Commons. To avoid allowing a "zombie government" to stagger on for years, unable to muster a majority to pass any new laws, the Fixed Term Parliaments Bill, says an election will be called 14 days after a lost confidence vote if no alternative government is able to show they have the confidence of MPs. Alternatively, MPs themselves could vote for an early dissolution - a power currently in the hands of the prime minister. Under the bill two thirds of the total number of MPs must back dissolution for an election to be called.


Researchers have identified dozens of "runaway stars" in the Milky Way, by combing the galaxy for the curved waves of material they plough before them.

These stars move at more than 30km/s relative to their surroundings, flung from their home neighbourhood by gravity or stellar explosions.
As they travel, material piles up in front of them, warms up and glows.
The team found that these bow waves make a useful signpost for spotting such speedy stars.
Their findings, presented at the 227th meeting of the American Astronomical Society in Florida, were based on survey images taken by Wise and Spitzer, two infra-red telescopes launched into orbit in the 2000s.
Breaking the Milky Way into one-degree squares, a large team of astronomers scoured these surveys for characteristic curvy red clouds. So far their search has spanned about one-third of the Milky Way's length and turned up more than 200 candidate "bow shocks".
They then chose 80 of those candidates to study in more detail using WIRO, a 2.3m infra-red telescope in Wyoming.
"We took a look at our arc-shaped objects and tried to find stars present in the centre of each image," said William Chick, a PhD student at the University of Wyoming.
"We were surprised to discover that over 95% of these stars were in fact hot massive stars, as we'd predicted."
Some of those were stars known from previous observations to be runaways - but many were not.
"These nebulae are probably tracing runaway stars we've never seen before, as well as giving us laboratories in which to discover what's creating these runaway stars, and how they evolve," Mr Chick said.
"It may be that our Milky Way is in fact swarming with these hot, runaway stars."
In fact, one of the new runaway candidates, apparently ploughing a supersonic wave of gas through our galaxy, is a binary star.
This is a very unusual observation and poses the intriguing question of what sort of force could propel twin stars violently through space, without pulling them apart.
Much about these runaways remains a mystery, Mr Chick explained; it is only thanks to infra-red surveys like those from Wise and Spitzer that the speedsters can now be picked out across the sky.
"We're getting to the point where we can find these objects reliably, and not have to rely on the most nearby, the brightest - such as Zeta Ophiuci," he said, referring to a well-studied runaway star discovered in the 1970s.
As well as extending their search across the rest of the Milky Way, Mr Chick and his colleagues hope to study some of their fresh discoveries in more detail.
For example, measuring how fast these stars are losing mass, in the very same solar winds that create the bow waves, will help illuminate their ultimate fate: whether they will explode as supernovae or collapse as black holes.
Their precise origins are also unknown, although astronomers have two likely explanations. Either a runaway starts life as a binary star but gets blown off-course when its partner explodes, or it simply gets flung into the distance by gravitational forces in a crowded stellar neighbourhood - perhaps even a slingshot around a black hole.
The team behind the new results hopes that having many more runaway subjects to study will help tease these possibilities apart.

Labour's newly elected Greater Manchester metro mayor, Andy Burnham, has appointed two deputies.

Mr Burnham, 47, was elected on Friday with 63% of the vote to lead the the Greater Manchester Combined Authority.
He named Sir Richard Leese as deputy for business and economy while Baroness Beverley Hughes will oversee policing and crime.
Councillor Rishi Shori, Bury Council's Labour leader, will take responsibility for young people and social cohesion.
Mr Burnham, who served in governments under Tony Blair and Gordon Brown, will control transport, housing and police budgets.
He will be paid £110,000 a year and take over the powers of the region's elected Police and Crime Commissioner, Tony Lloyd.
Who are the six new combined authority mayors in England?
Combined authorities are groups of councils working together to assume powers, devolved from central government,
Greater Manchester's authority will have control over a £6bn health and social care budget and also has an adult skills budget, powers over apprenticeship grants for employers, strategic planning powers, and  transport.
The Liverpool-born politician said the region "will be the modern industrial capital of the country - digital, green, and young" and he "will put young people at the centre of everything we do".
Mr Leese said he had been "working on the devolution agenda" and although "we need a lot more control", he will do everything he can to make devolution "an enormous success".
Former home office minister, Baroness Hughes, said she was "honoured" to be part of "a new era of politics" and face the "challenging" police and crime brief.
Mr Shori said he will create a "youth combined authority" because "we can't afford to lose and ounce of the potential of our young people... the future belongs to young people and they are going to help shape it".
Mr Burnham, who has been MP for Leigh in Wigan since 2001, will not stand in next month's general election.

The finance minister has said he is disappointed that local councils will not get powers for regeneration in their areas.

When councils were reduced from 26 to 11, responsibilities like planning were passed to them by the government.
However, on Wednesday, Communities Minister Paul Givan said regeneration will remain an executive function.
Speaking on the BBC's The View, Máirtín Ó Muilleoir said that decision was regrettable.
"He knows my position on the regeneration of powers to local councils, he knows I'm disappointed. It is my belief that the councils would be stronger partners.
"Paul isn't convinced of that at the minute. I work with councils every day. I admire their ambition and I'm going to continue to work with them."
Mr Givan said he wanted regeneration to remain with the executive for the time being.
"This was a power which had been discussed in the last mandate," he said.
"There were numerous attempts to bring forward legislation and there wasn't consensus to do that and I'm clear now in this new mandate that I don't want to be involved in tinkering around who gets what, where the budget should be divided, it's about getting things done."


Three Kenyan men who stripped and attacked a woman in a bus have been sentenced to death by a magistrate in the capital, Nairobi.

The death sentence was imposed after the three were convicted of robbery with violence.
A further 25-year sentence for stripping the woman was suspended due to the death penalty.
The incident was recorded and shared widely on social media three years ago, sparking nationwide protests.
Hundreds of women, some in tight fitting clothes, marched through Nairobi, rallied by the hash tag #MyDressMyChoice.

Stripping videos outrage Kenyans
Chief magistrate Francis Andayi said that those convicted had taken part in a "senseless and uncouth attack that they seemed to enjoy because they were cheering as they stripped the woman", the privately owned Daily Nation newspaper reports.
This episode was part of a wave of sexual assaults in Nairobi during 2014.
Anne Soy, BBC News, Nairobi
Most people have been in support of today's ruling, however, one man told  the BBC that the sentence was unfair and that women need to dress according to Kenyan traditions.
Cases of sexual assault of this nature have greatly reduced recently. We have not had any reported cases of harassment for alleged provocative dressing since 2014.
And while death penalties are still passed in Kenyan courts, no executions have actually been carried out since 1987.  Last year President Uhuru Kenyatta commuted all death sentences in the country to life imprisonment.
So the three men may be set for a long time of reflection in prison.


The UK is to give another £5m to the relief effort in Nepal, bringing Britain's contribution to £15m.

More trauma medics and heavy lifting equipment to help move supplies at Kathmandu airport will be included in the aid package, the government said.
More than 5,000 people are now known to have died in Saturday's earthquake.
The latest pledge, which comes after leading UK aid agencies launched a TV appeal for donations, means Britain now tops the league of financial donors.
Many other countries have also sent emergency aid, including India, which has 13 of its military helicopters scouring the most remote areas of the disaster zone.
BBC world affairs correspondent Naomi Grimley said as the dust settled, it was becoming clearer what was needed on the front-line of the rescue and relief effort.
Two of the biggest problems were the lack of doctors, and congestion at Kathmandu airport, she said.
The UK's additional £5m aid package will include:
• A 30-strong medical team carrying eight tonnes of equipment, including medical supplies, bandages, a generator and tents
• Airfield handling equipment, including two forklift trucks to help with moving aid supplies off aircraft
• An agreement to fund humanitarian experts in water, health and sanitation to help coordinate the relief effort
Announcing the additional aid, International Development Secretary Justine Greening said the UK was playing a leading role in response to the Nepal earthquake.
Nepal has declared three days of national mourning for the victims of the 7.8-magnitude earthquake and subsequent aftershocks. Officials say the death toll has now passed 5,000, but could reach 10,000, with at least 8,000 people injured.
Among the dead are 18 climbers who were at Mount Everest base camp when it was hit by an avalanche triggered by the quake.
The Foreign Office says it is is investigating reports a Briton living overseas was killed in the earthquake.
Foreign Secretary Philip Hammond said at least 500 Britons had been accounted for but staff were contacting tour operators and hospitals to trace others.
He is expected to chair a meeting of the Cobra emergency committee on Wednesday.
Mr Hammond said the Foreign Office had estimated there were between 500 to 1,000 British nationals in Nepal but there was "no single co-ordinated list".
Officials had assisted more than 250 British nationals and 583 "either have left the country or are not in the country or are accounted for and safe in the country", he said.
The BBC is aware of about 30 British or Irish families who are still waiting to hear from relatives.
The televised appeal was launched on Tuesday by the Disasters Emergency Committee, an umbrella organisation which brings together 13 UK aid charities to deal with international crises.
Actress Joanna Lumley, who has campaigned for the rights of Nepalese British Army Gurkhas, filmed appeals aired on the BBC, ITV, Channel 4, Channel 5 and Sky. A website and donation line was launched earlier.
The UK government has promised to match the first £5m of public donations to the DEC appeal.
Downing Street has already given £5m to help people affected by the earthquake. It said it had released £3m to address immediate needs and that £2m would be given to the Red Cross.
A team of more than 60 search and rescue responders and medical experts deployed by the Department for International Development are in Nepal.
An RAF plane carrying aid supplies and Army troops has also been sent to the country.


It's one of the highlights of the British racing and social calendar, renowned for its royal connections and formal attire.

Its associations with DJ sets and a young, festival-going crowd are rather less well established.
But a new enclosure at this year's Royal Ascot will seek to attract a new generation of racegoers by offering a "party atmosphere" and a "more vibrant feel".
The Village Enclosure will provide a range of attractions, including eateries, bars, social areas and DJs.
The "popular formality of dress code" of the Queen Anne enclosure - the suits, the fascinators - will remain, but with a festival touch, say organisers.
"Best racing, best party, is the aspiration," said Nick Smith, Ascot's director of racing and communications.
"But very much within the parameters of what makes Royal Ascot special and genuinely unique."
Organisers expect there to be a "natural synergy" towards the younger demographic, although they want "repeat visitors and happy visitors" rather than large numbers.
"We specifically want to encourage people with racing interest alongside those to whom the party atmosphere will appeal - hopefully one and the same in many cases," added Smith.
This year's Royal Ascot runs from Tuesday, 20 June to Saturday, 24 June.


Myanmar, also known as Burma, was long considered a pariah state while under the rule of an oppressive military junta from 1962 to 2011.

The generals who ran the country suppressed almost all dissent - symbolised by the house arrest of opposition leader Aung San Suu Kyi - and stood accused of gross human rights abuses, prompting international condemnation and sanctions.
A gradual liberalisation process has been under way since 2010. The country is expected to see a major shift after the government changed hands early in 2016.
The dominance of the largest ethnic group, the Burman or Bamar people, over the country's many minorities has been fuelling a series of long-running rebellions, although a gradual peace process yielded a draft ceasefire deal in 2015.
Population 48.7 million
Currency Kyat
Area 676,552 sq km (261,218 sq miles)
Major language Burmese, minority languages
Major religions Buddhism
Life expectancy 64 years (men), 68 years (women)
President: Htin Kyaw
Htin Kyaw was sworn in as president in March 2016, ushering in the first democratically elected government into office after decades of military rule.
Rightfully, the job belonged to Nobel laureate Aung San Suu Kyi, who has been the face of the pro-democracy movement and who endured decades of house arrest and harassment by military rulers without ever giving up on her non-violent campaign to unseat them.
But Suu Kyi was barred by the constitution from becoming president, and she made it clear that whoever sits in that chair will be her proxy. She has said repeatedly she will run the government from behind the scenes.
Htin Kyaw will be remembered by history as the first civilian president for Myanmar and the head of its first government to be elected in free and fair polls.
The military retains considerable amount of power in the government and parliament.
Myanmar's media have seen a gradual easing of strict state controls imposed after the 1962 military coup.
Under reforms introduced since 2011 by a new government, Myanmar has unblocked international news websites, emigre news websites and YouTube. In 2012, it lifted pre-publication censorship for the press and allowed privately-owned daily newspapers to publish.
But the state still controls the main broadcasters and publications.
1057 - King Anawrahta founds the first unified Myanmar state at Pagan and adopts Theravada Buddhism.
1531 - Toungoo dynasty reunites country as Burma.

1948 - Burma becomes independent.
1962 - The military junta takes over, initially in the shape of a single-party socialist system.
1990 - Opposition National League for Democracy (NLD) wins landslide victory in elections, but the military ignores the result.
2011 - The military hands over to a nominally civilian government following elections the previous year.
2015 - Elections. Opposition National League for Democracy - led by Aung San Suu Kyi - wins enough seats in parliament to form a government.


It is time to "blow away" all the "nonsense" that prevents police from properly pursuing extremist suspects, London Mayor Boris Johnson has said.

In a BBC interview, Mr Johnson was asked about Londoner Siddhartha Dhar, who is thought to have fronted a so-called Islamic State propaganda video after fleeing the UK while on bail.
He said laws governing bail were "pretty ineffective" and police work was hampered by "very uppity lawyers".
The UK needed a more "robust" approach.
The UK's security authorities have faced mounting questions over how Mr Dhar was able to leave the UK in 2014 while on police bail, one of the conditions of which was handing over his passport.
Muslim convert Mr Dhar, also known as Abu Rumaysah, had been arrested on suspicion of encouraging terrorism, but later travelled to Syria.
"Police bail's a pretty ineffective system," Mr Johnson told BBC Radio London.
"Under the law, they have various restrictions under human rights as to what they can actually do.
"And the police are constantly monitored by very, very uppity lawyers... who are drawn to vindicate the rights of their clients."
He pointed out that 750 British nationals had gone to Syrian territories of Islamic State - which the government refers to as Daesh.
"When you've got somebody like this who's a member of... whatever organisation, and we've seen what's happening in the Daesh territories in Syria, let's not monkey around, let's make sure we follow them," he added.
"I'm not saying 'stuff their human rights' because that's not the way we do things in this country. But let's be pretty robust in our approach."
Former director of public prosecutions Lord Macdonald said he believed terror suspects should not be granted police bail unless the decision was signed off by a prosecutor.
"Given the sensitivity of these cases, and their obvious national security implications, any consideration of bail requires special care," he said.
"The Siddharta Dhar case shows that it is not sufficient or safe for the police to decide this question for themselves."
Nazir Afzal, who was chief crown prosecutor in north-west England from 2011 until last year, said there was a "strong case" for prosecutors to have the final say.
A CPS spokesman said it worked "very closely" with the police on all terrorism cases, including pre-arrest, but any decision on bail conditions before a charging decision was a matter for the police.
Earlier this week, official sources told the BBC that Mr Dhar, from Walthamstow in east London, was the focus of investigations into the video, which purported to show the killing of five men.
IS has said the men had been spying for the UK.
IS seized large swathes of territory in Syria and Iraq in 2014, when it formally declared the establishment of a "caliphate" - a state governed in accordance with Islamic law, or Sharia.
The group has previously released propaganda videos of killings, including footage showing the apparent beheading of two US journalists, James Foley and Steven Sotloff, and two British aid workers, David Haines and Alan Henning.


Amazon, in its third decade of business, dominates the world of online shopping.

But an actual bricks and mortar Amazon store? That's still as rare as an A-list celebrity sighting.
The company opened its seventh US bookshop in New York on Thursday, drawing a steady stream of selfie-snapping gawkers, tourists and loyal shoppers who revelled in the novelty experience of shopping in person.
"It makes it feel more accessible," said Amanda Martinez, 25, of New York, who arrived before the store opened and walked out later with a JJ Abrams novel. "It's already accessible because it's online but it's nice to go inside and walk around."
Amazon opened its first bookshop in Seattle in 2015. By the end of the year, it plans to have 13 in the US. It's also expanded its physical footprint on university campuses and is experimenting with grocery and convenience shops.
Bricks and mortar retail remains a marginal part of Amazon's business - and that's not likely to change anytime soon, said analyst Tuna Amobi, who follows the company for CFRA Research.
But Mr Amobi says even on a small scale, a real store has benefits, including boosting brand awareness and exposing people to Amazon's Prime subscription service.  Prime members get the online prices in the store, while non-members must pay the list price for books.
"There's an opportunity to get their platform closer to the consumer and interact, engage, at a very minimal investment," he said.
For Amazon's smaller rivals, which have stepped up face-to-face events such as author readings to survive, the company's physical expansion also adds to the pressure, he explained.
"It's been an ongoing process [of disruption] frankly over the last decade," he said. "This is just going to ... accelerate that."
Leigh Altshuler, spokeswoman for the Strand Book Store - a New York institution founded in 1927 - said the Strand knows it cannot rest on its laurels.
But she thinks the typical Amazon customer is looking for something different to those drawn to independent shops like hers: "We're not going anywhere. We're ... not just a bookstore, but a culture and a community."
Jennifer Cast, the vice-president of Amazon Books, said the company's "customer-obsessed" focus is driving the real-world expansion.
People have been asking for a place to check out books and test-drive Amazon's tech products, such as the Kindle e-reader, she says.
Amazon also has a mountain of data on what people are reading to put to use in stocking the store.
At the New York shop, which is tucked away on the third floor of one of Manhattan's most upmarket shopping malls, the company organises books into new kinds of categories, such as page turners - books that Kindle-readers finish in three days or less.
She says the goal of the shop, where customers can pay by credit card or on the Amazon App, is to be "a discovery mecca for customers".
"People have asked us, 'Is this just a big showroom?'" Ms Cast said. "I just say: 'Look how many books are on the shelves. Does this look like a showroom?' No - this is a store."
Ms Cast wouldn't say whether the shops are profitable or how many more stores Amazon might be contemplating.
Xiupeng Zhang, 28, of New York is an Amazon Prime member who stopped by to buy a Sheryl Sandberg book.
For him, the ability to pick up his purchases straight away without having to wait for them to be delivered, combined with low, online-world prices has long-term appeal: "It's like the future of retail."


An acrobatically taken try from Matty Russell helped Warrington overcome Championship side Halifax and maintain their perfect record in The Qualifiers.

Peta Hiku put the Super League hosts ahead and, after both sides were denied a try by the video referee, Chester Butler made it 4-4 at the break.
Chris Hill restored Wolves' lead, only for Butler to respond again.
Russell brilliantly rose to claim the hosts' third from a cross-field kick, before Andre Savelio completed the win.
Warrington Wolves boss Tony Smith:
"We were a little flat in the first half and we had to respond in the second half and we did. We probably didn't nail a few chances in first half when we were held up two or three times over the line and had some dubious obstruction calls and if you nail those it gives the whole game a different perspective.
"It was a tough game because the ruck was slow and Halifax did what they had to. Credit to how the defended because they knew they needed to slow us down to keep in the game and they were allowed to.
"Playing against a Championship team you learn some stuff, but I thought we had a Championship standard referee today and that's going to happen to us from time to time.
"We have to be able to cope with that and come out on top regardless of that. Halifax haven't given up all year and that's why they are in the position they are in terms of making it to the Qualifiers and Richard Marshall has done a great job with them there."
Halifax boss Richard Marshall:
"We are a proud bunch and I'm a proud coach today and I thought we had the opportunity to win the game.
"In the first half with some smarter decisions with ball we could have scored a couple more tries. We did force the pass, but we had to when you are playing one of the best teams in this competition and in Super League.
"Warrington have some world class players, but I thought our enthusiasm was world class and our attitude to defend for your team-mates was outstanding and that goes a long way with me.
"We didn't win the game, but we certainly got a few wins internally in that performance."
Warrington Wolves: Ratchford; Russell, Hiku, Atkins, Lineham; Patton, Brown; Hill, Smith, Sims, Jullien, Hughes, Westwood.
Replacements: Philbin, Dwyer, Savelio, G King.
Halifax: Saltonstall; Butler, Woodburn-Hall, Tyrer, Worrincy; Murrell, Johnston; Morris, Kaye, Fairbank, Grady, Barber, Grix.
Replacements: Mammone, Sio, Moore, Boyle.
Referee: Robert Hicks.


"You're crazy" was what people said when they found out that Nathan Blecharczyk was working on a website which would allow people around the world to rent their spare room or property to strangers.

Almost eight years later he doesn't look quite so crazy. Airbnb - the room letting website he helped to create - has been used by 60 million guests in 190 countries around the world, and has been valued at a staggering $25.5bn (Â£17.8bn; â‚¬23.4bn).
That's more than many of the established players in the hotel sector.
Yet in the early days Mr Blecharczyk said the idea was ridiculed by both investors and friends alike.
"So many people thought this was a crazy idea when they first heard it. They said certainly no one is going to allow strangers into their home, and so it was dismissed very quickly.
"A lot of these disruptive innovative ideas can easily be dismissed at first glance because they're so novel that you just think it's not possible."
It all began in 2007 when fellow co-founders Brian Chesky and Joe Gebbia couldn't afford the rent on their San Francisco apartment.
There was a design conference coming up in the city and all the hotels were full so they put some air mattresses in the loft and created a simple website to advertise the room for rent.
Instead of a bed and breakfast they called it an airbed and breakfast - the name and the idea was born.
The fact that a company which didn't even exist a decade ago can now be one of the big players in the accommodation industry is indicative of how technology is shaking up the status quo in established industries.
Taxi hailing app Uber, commercial music-streaming service Spotify and the mighty Amazon have all wreaked havoc on their less technology-savvy rivals.
The changes mean that the qualities required in the boardroom are also shifting.
Traditionally the best route to the top has been from a management or financial background, but increasingly tech know-how is valued.
"Suddenly all of this technology that you used to have to go to your computer to use is going to be embedded in every aspect of your life and really driving the offline world.
"So I think as a CEO thinking about where the future is going to lie and knowing that it's going to be something completely different today is important," says Mr Blecharczyk.
It's a shift that CEO coach Steve Tappin, who works with many top chief executives around the world, says he's noticed.
"In the past, the idea of a geek in the boardoom was unthinkable. But technology is having a profound impact not just on products but the way businesses are run," he says.
Telstra chief executive Andrew Penn rose to the top via the traditional route; he was previously the Australian telecommunications firm's chief financial officer.
Nonetheless, he says that having a good grip on the technical side of the business is essential to his role.
"You've got to get your head around it.
"I don't know that means we necessarily all need to become software coders, but you do need to know enough as a CEO of a company to ask the right questions, to formulate a point of view about whether or not we had the right strategy, to get the right quality people around you that can make a difference from a technology standpoint."
Of course, as the rise of new start-ups such as Airbnb indicate, tech is also a fast-moving world. Staying on top of it means not only being aware of the changes, but ensuring the company is agile enough to react to them.
Victor Koo, chief executive of video-sharing giant Youku Tudou, often dubbed China's YouTube, says since the firm launched just under a decade ago the demands of its audience have already shifted dramatically.
In 2006, the company's customers were accessing content almost entirely on their desktop computers, now more than 60% of users access the firm's content via their mobiles.
He says such a rapid pace of change means that the structure of the organisation and the traditional reporting hierarchies within it need to be shaken up, even if temporarily.
"When you draw an organisational chart - it's really things that we came up with back in the industrial change, right?" he says.
"And we're in the internet world where the world's changing very quickly, and the traditional kind of reporting lines and kind of pyramid structure needs to be adapted."
He says this could mean short-term changes, such as bringing together people for a particular project, before they return to their usual roles.
To help keep up with the rapid pace of change, the Chinese company has created "quick task teams" which work across different departments, can brainstorm ideas and come up with new ways of doing things.
His advice to fellow chief executives is "act now".
"In terms of mistakes it's often not acting quickly enough. I'm not saying you need to bet the farm. But if you spend too much time thinking about it the opportunity has already passed," he says.
This feature is based on interviews by CEO coach and author Steve Tappin for the BBC's CEO Guru series, produced by Neil Koenig.


The parents of a man murdered in the Sydney cafe siege have stormed out of an inquest after a police chief said the gunman had "had the same rights as any other person".

In December 2014, self-styled Islamist Man Haron Monis held 18 people hostage inside the Lindt Cafe in Martin Place.
Heavily armed police raided the building 17 hours later after Monis shot cafe manager Tori Johnson.
The inquest is investigating the police response to the situation.
Monis was shot dead by police during the raid, while a second hostage, Katrina Dawson, was killed by stray bullet fragments fired by police.
Under cross examination on Tuesday, the forward commander in charge of the siege operation was asked why he did not order the raid earlier, when Monis fired a shot in the direction of six escaping hostages.
The detective chief superintendant, who cannot be named for legal reasons, said it had been "a high stakes game". When challenged on his use of "game" he said it "may not be the right word".
Questions about why police snipers did not attempt to shoot Monis have been heavily discussed during the inquest.
A barrister acting for the Johnson family put it to the police commander that his mission had been to secure the safe release of the hostages rather than the welfare of the gunman.
"I can't ignore Man Monis as an individual, he had the same rights as anyone else," the police officer replied.
The comments prompted Ken Johnson and Rossie Connellan to rise from their seats and leave the court.
Ms Connellan yelled at the officer: "You're an absolute disgrace."
How the Sydney siege unfolded
The commander had previously said the cafe siege had the hallmarks of a domestic incident rather than terrorism, despite the fact that Monis asked to be given a flag of the so-called Islamic State (IS) militant group.
He said he had been advised by a psychiatrist that the siege was "final posturing" by Monis in order to gain some "street cred" before a likely jail sentence.
Monis had been facing dozens of sexual assault charges plus charges of being an accessory to the murder of his ex-wife.
"Our experience internationally is IS does not have sieges, they have active armed offender situations," said the officer.
"They commence with violence, high levels of death, whether by a person-borne bomb or automatic gunfire - they are not siege situations.
The officer said he believed at the time that if negotiators could speak directly with Monis, they could achieve a peaceful end.
On Wednesday, he told the inquest: "Three people lost their lives because of me. I reflect on this every day but I don't know what I could have changed."
The inquest, before Coroner Michael Barnes, is continuing in Sydney.


Have you ever wondered what Viking poo looks like?

11 April 2017 Last updated at 15:31 BST
It is one of the star attractions at the Jorvik Viking Centre in York, England.
Examination under the microscope shows it contains pollen grains and the remains of cereal bran.
The poo also contains the eggs of a nasty parasite, which would have caused this particular Viking an upset tummy.

Billy Ogilvie - the manager who led East Kilbride to a dream Scottish Cup tie against Celtic - will leave the Lowland League club on 20 March.

The K Park club say "work commitments" mean the 55-year-old taxi driver cannot perform the role next season.
Ogilvie will leave his post after the East of Scotland Qualifying Cup final against Spartans at Albyn Park.
"The club will now begin the process of finding a replacement manager," said East Kilbride secretary Dave McKenna.
"Over this and last season, Billy has been fully committed to helping the club progress and his efforts and enthusiasm have been outstanding.
"We wish Billy every success for the future and he will always be welcome at EKFC."
Media playback is not supported on this device
Kilby beat Forres Mechanics, Stenhousemuir and Lothian Thistle Hutchison Vale on their journey to a Scottish Cup fifth-round match against Celtic.
The last-16 tie took place at Airdrie's Excelsior Stadium and two scrappy goals by Leigh Griffiths and Colin Kazim-Richards helped Ronny Deila's men progress.
East Kilbride are currently fourth in the Lowland League.
"As happens towards the end of any season, meetings take place in preparation for the new season coming up," said McKenna.
"A major part of this is to secure the services of existing players and discuss what, if any new recruits are needed.
"During these discussions, first-team manager Billy Ogilvie informed the club that due to work commitments he would not be able to continue in post for the new season.
"Billy was very keen to see out the current season and it is to his credit that he was willing to do so. However, he accepts that the club needs to prepare now for the new season.
"This means Billy will remain in post up to the cup final v Spartans on Sunday 20 March."
Ogilvie, who succeeded Iain King in 2014, has three games left as East Kilbride manager. They play BSC Glasgow and Edinburgh City in the league before the cup contest with Spartans.


Humans could become extinct if sperm counts in men continue to fall at current rates, a doctor has warned.

Researchers assessing the results of nearly 200 studies say sperm counts among men from North America, Europe, Australia, and New Zealand, seem to have halved in less than 40 years.
Some experts are sceptical of the Human Reproduction Update findings.
But lead researcher Dr Hagai Levine said he was "very worried" about what might happen in the future.
The assessment, one of the largest ever undertaken, brings together the results of 185 studies between 1973 and 2011.
Dr Levine, an epidemiologist, told the BBC that if the trend continued humans would become extinct.
"If we will not change the ways that we are living and the environment and the chemicals that we are exposed to, I am very worried about what will happen in the future," he said.
"Eventually we may have a problem, and with reproduction in general, and it may be the extinction of the human species."
Scientists not involved in the study have praised the quality of the research but say that it may be premature to come to such a conclusion.
Dr Levine, from the Hebrew University of Jerusalem, found a 52.4% decline in sperm concentration, and a 59.3% decline in total sperm count in men from North America, Europe, Australia and New Zealand.
The study also indicates the rate of decline among men living in these countries is continuing and possibly even increasing.
In contrast, no significant decline was seen in South America, Asia and Africa, but the researchers point out that far fewer studies have been conducted on these continents. However, Dr Levine is concerned that eventually sperm counts could fall in these places too.
Many previous studies have indicated similar sharp declines in sperm count in developed economies, but sceptics say that a large proportion of them have been flawed.
Some have investigated a relatively small number of men, or included only men who attend fertility clinics and are, in any case, more likely to have low sperm counts.
There is also concern that studies that claim to show a decline in sperm counts are more likely to get published in scientific journals than those that do not.
Another difficulty is that early methods of counting sperm may have overestimated the true count.
Taken together these factors may have created a false view of falling sperm counts.
But the researchers claim to have accounted for some of these deficiencies, leaving some doubters, such as Prof Allan Pacey of Sheffield University, less sceptical.
He said: "I've never been particularly convinced by the many studies published so far claiming that human sperm counts have declined in the recent past."
"However, the study today by Dr Levine and his colleagues deals head-on with many of the deficiencies of previous studies."
But Prof Pacey believes that although the new study has reduced the possibility of errors it does not entirely remove them. So, he says, the results should be treated with caution.
"The debate has not yet been resolved and there is clearly much work still to be done.
"However, the paper does represent a step forward in the clarity of the data which might ultimately allow us to define better studies to examine this issue."
There is no clear evidence for the reason for this apparent decrease. But it has been linked with exposure to chemicals used in pesticides and plastics, obesity, smoking, stress, diet, and even watching too much TV.
Dr Levine says that there is an urgent need to find out why sperm counts are decreasing and to find ways of reversing the trend.
"We must take action - for example, better regulation of man-made chemicals - and we must continue our efforts on tackling smoking and obesity."

Director Peter Jackson has defended shooting The Hobbit trilogy in a new format at 48 frames per second after a mixed response from film critics.

Since 1927, the standard frame rate - the number of frames or images that are projected per second - has been 24 frames per second.
"24 frames is jarring to me now," Jackson told the BBC.
"It looks primitive. Change is good, it takes people some time to get used to it," he added.
"Ultimately, it's not critics who are going to decide if this (the new format) is going to be adopted or not, it's the audience."
"(There will always be) people who have a particular strong feeling that film should be unchanged and that we got it right in 1927, just like there are people who play vinyl records still, whereas most of the world has moved to CDs and we got used to that."
However viewers will only be able to watch the film being projected at the increased frame rate in a small proportion of cinemas. Most will be showing the film at the traditional rate of 24 frames per second.
The Independent said 48 frames per second was "kitsch and alienating", while the Telegraph said it gives the film "a sickly sheen of fakeness".
But others, including Wired magazine loved it, saying: "Middle-earth in 3D looks so crisp it's like stepping into the foreground of an insanely gorgeous diorama.""
The Hobbit: An Unexpected Journey, the first in Jackson's series of three films adapting JRR Tolkien's classic book, opens in cinemas in the UK on Thursday and in the US on Friday.
Andy Serkis, who reprises the role of Gollum from the Lord of the Rings film, concurred with Jackson on the 48 frames per second.
"It's so immersive, I find it really magical and really engaging," he said. "It has a level of reality that it is unsurpassed... some people will find it challenging but... it's a matter of time and there won't be a discussion any more."
Despite being happy with the end result, Jackson said he did not expect The Hobbit to win any Oscars next year.
"I think they gave us our Oscars for Return of the King (the final instalment of the Lord of the Rings trilogy).
"I don't think there'll be any Oscars this time round which is fine, it actually takes the pressure off.
"It helped with Lord of the Rings that there was a weight and a gravitas to the whole story which The Hobbit doesn't have... but some of the technical categories are superb so hopefully we'll feature in those."
Meanwhile, a parody of The Hobbit: An Unexpected Journey, was stopped from going on sale when a US District Court in California granted a temporary restraining order on Monday.
Global Asylum, a film company that makes parodies of blockbuster films such as Transmorphers, based on Transformers, was set to release Age of the Hobbits on Tuesday on DVD.
The studios making The Hobbit - Warner Bros and New Line MGM, along with producer Saul Zaentz - had asked the court to prevent the release.
The court for the central district of California granted their request, as Judge Phillip S Gutierrez said that they had satisfied the legal standard for a temporary restraining order.
The applicant has to demonstrate that there is a valid copyright infringement claim, that there would be danger to the plaintiff if the order is not granted, that the plaintiff would suffer more and that the order would advance the public interest.
Global Asylum had argued that its film was not trying to deceive viewers or use the debut of The Hobbit: An Unexpected Journey to boost its own profits.


BBC Sport's football expert Mark Lawrenson is pitting his wits against a different guest each week this season.

Lawro's opponent for this weekend's Premier League fixtures is American hip hop artist Fatman Scoop, who has been taking part in Sport Relief's Battle of the Five-A-Sides.
During the match, Fatman Scoop had a few words to say about one game in particular this weekend. He told BBC Sport: "Arsenal are going to get beaten so bad, it's going to be disgusting."
Robbie Savage and Alan Shearer have kicked-off a 57-hour five-a-side game for Sport Relief.
The match, between BBC Radio 5 live and Match of the Day, was being played outside BBC MediaCityUK in Salford.
Also up against Lawro this week is 1Xtra DJ Nick Bright.

A family who left Iraq to find a safer life in Europe have been reunited with their missing cat.

22 February 2016 Last updated at 12:29 GMT
The Al-Alaf family left Mosul in Iraq carrying their cat Kunkush.
They all travelled to Turkey and even crossed the Aegean sea together to the Greek island of Lesbos.
It was here that Kunkush slipped out of the basket and disappeared.
After travelling for three months the family finally made it to Norway where they had settled without their pet cat.
But thanks to a social media campaign and a German animal rights group the family have been reunited with their favourite feline.
Take a look.


A man accused of murdering his baby son, who died after being "thrown or swung into something hard", did nothing to hurt him, a court heard.

Robert Hinz, of Bournemouth, said he tried to help three-month-old Julian, who had suffered fatal head injuries.
The baby died at Southampton General Hospital on 9 April 2016, Winchester Crown Court heard.
Mr Hinz, 34, of Carysfort Road, denies murder and three counts of causing grievous bodily harm with intent.
The court has heard the pair were alone together at home while Julian's mother Monica was out shopping.
Julian was later found with severe skull fractures and died in hospital the following day.
He was killed in "a few moments of anger and violence" when he was "thrown or swung into something hard", prosecutors have told Mr Hinz's trial.
Taking the stand, Mr Hinz said:  "I do not remember what happened in the bedroom but I didn't murder my son.
"He wasn't breathing when I picked him up, he was floppy.
"I started to do resuscitation, blowing in his mouth, pressing on his chest."
Mr Hinz denied he often lost his temper but admitted he had damaged his flat when the paramedics arrived.
He said: "I took out my frustration on the door and the wall".
The jury previously heard Julian had also sustained fractured ribs on previous occasions, which the prosecution said would have been caused by "squeezing".
The trial continues.

India's cabinet has approved plans to privatise Air India.

The debt-laden airline has been struggling to become profitable amid growing competition from low-cost rivals.
Finance minister Arun Jaitley said the government had given an "in-principle" approval for the stake sale.
India will form a committee to decide on the details, including the size of the government's stake to be sold, he said.
The committee will also decide whether India will write off some or all of Air India's 520bn rupee (Â£6bn, $8bn) debt pile.
Prime Minister Narendra Modi's government has been looking into ways to privatise Air India, which was given a $5.8bn bailout in 2012 and relies on taxpayer funds to stay afloat.
Privatisation plans have been abandoned before, however, and unions have threatened wide-ranging protests if ministers push ahead this time.
Once the country's only airline, Air India has lost market share to new entrants and suffered from a reputation for poor service and cancelled flights.
It remains India's biggest international carrier, flying to 41 destinations, and has just under a fifth of the market.
Air India has 14.6% of the domestic air travel market.


England captain Eoin Morgan says his side have the confidence to beat New Zealand in Cardiff on Tuesday and reach the Champions Trophy semi-finals.

England's last one-day international tournament meeting with the Black Caps ended in an eight-wicket defeat at the World Cup in February 2015.
Morgan says that heavy loss was like "men against boys", with New Zealand going on to reach the final.
"It's completely different now, two years down the line," said Morgan.
England recovered later that year to beat Brendon McCullum's tourists 3-2.
Another victory in Tuesday's match, which starts at 10:30 BST, would put them into the Champions Trophy last four, after New Zealand's game with Australia on Friday was abandoned because of rain.
"We've got a completely new team, pretty much," added Morgan.
"A lot of it has to do with confidence. We come into this tournament full of confidence.
"The dominant factor in New Zealand was that they had that confidence, whereas we didn't."
Morgan's side face Australia at Edgbaston on Saturday in their final Group A game.
Steve Finn has replaced injured all-rounder Chris Woakes in the squad and Morgan says the Middlesex seamer was an automatic choice.
"It was backing up consistency in selection and trying to get guys together as a group that we've showed trust in over the last couple of years," he said.
"We've tried to go like-for-like as often as we can. But when we can't, we go for a guy we can throw the ball to at any stage in order to try to make an impact in the game.
"Finny is one of those guys, and I'd have no hesitation in playing him if we felt it was the right thing to do."


Bournemouth boss Eddie Howe says he is identifying transfer targets for next season - and is unlikely to re-sign England midfielder Jack Wilshere

Wilshere, 25, has been on loan with the Cherries most of the season from Arsenal but has missed the end of the campaign with a fractured leg.
"I think it's going to be really difficult for us," said Howe, when asked on Friday about the chances of re-signing Wilshere.
"We wish him well for the future."
After signing at the end of August, England international Wilshere made 27 league appearances for the Cherries - including five as a substitute - without scoring, although he managed two assists.
Scans revealed a hairline crack in Wilshere's left fibula after he was injured during a 4-0 defeat at Tottenham on 15 April.
"When we signed him on loan, and I have said this many times, the plan was for him to stay for a season and then to go back to Arsenal to evaluate his future," added Howe, whose side have secured a third straight season in the Premier League.

Bournemouth are 11th in the Premier League table, eight points above the relegation zone, with two games remaining at home to Burnley (15:00 BST) on Saturday and away to Leicester on 21 May (15:00 BST).


Former Kilmarnock boss Allan Johnston is the new manager of Dunfermline Athletic, signing a one-year deal.

The Scottish League One club recently announced that John Potter would be stepping down from the manager role to his former post as head coach.
Neil McCann, who started the season as assistant to Potter's predecessor Jim Jefferies, is leaving the Pars.
"The club is forward thinking, they obviously want to achieve success. It's the perfect fit for me," said Johnston.
Johnston, 41, won Scotland's third tier and promotion with Queen of the South in 2013 and then joined Killie.
However, he left Rugby Park in February a day after announcing his intention to depart at the end of the 2014-15 season.
Johnston was upset that forward Robbie Muirhead was sold to Dundee United on transfer deadline day, saying: "I never found out Robbie was away until five past 12 [midnight]."
The former Scotland international played for both Queens and Kilmarnock as well as Hearts, Rangers, St Mirren, several English clubs and Rennes in France.
Dunfermline, one of only two clubs with full-time playing staff, started the season with Jefferies in charge and were favourites for the title.
However, the former Hearts and Kilmarnock boss resigned in December, with Potter taking over, and finished the campaign in seventh place - 11 points adrift of the play-off places.
Johnston told BBC Scotland: "I was interested in the job, I put in my CV, and I got the interview, so absolutely delighted to get it. The size of the club there's always going to be people interested.
"I thoroughly enjoyed me time at all the clubs I've been at. Queen of the South, really successful. Kilmarnock, I think I left them in a good position.
"The main focus is Dunfermline now and obviously try and achieve promotion."
The East End Park club are now community-owned club in 2013 following administration.


Sale Sharks have signed Wales and former Cardiff Blues second row Lou Reed on a two-year deal.

The 28-year-old, who won the last of his five Wales caps in 2013, started his career at Scarlets and had been with the Blues for four years.
Reed will help cover the loss of Juandre Kruger, who pulled out of a move to the Sharks for family reasons.
"Lou came highly recommended by [former Sale scrum-half] Dwayne Peel," said director of rugby Steve Diamond.
"He is a big physical guy who will be a very abrasive addition to the squad."
Reed added: "After playing for Cardiff and Scarlets I am really looking forward to playing for Sale in the Premiership. I have been training all week and have been welcomed by everyone at the club."


A leading Conservative EU exit campaigner has criticised "petty tabloid smears" by the Remain campaign and suggested Downing Street is behind "vicious briefings" against his side.

MP Steve Baker called for an end to "personal nastiness" warning "deep divisions" in the party were emerging.
Both campaigns have traded barbs - with Boris Johnson at odds with David Cameron and Lord Heseltine this week.
A Downing Street spokesman said "we don't accept" Mr Baker's claims.
In other EU referendum campaign developments:
The government is campaigning for a vote to remain in the EU in the 23 June referendum and Prime Minister David Cameron, whose party is divided on the issue, has previously called for a "respectful" debate.
But in an article for the ConservativeHome website, Mr Baker, the co-chairman of Conservatives for Britain, said he had found the recent debate "breathtakingly disheartening".
Former London mayor Mr Johnson also sparked a row by referring to Barack Obama's "part-Kenyan" ancestry after the US president backed a vote to remain, and described international figures backing the government's case as appearing in "Downing Street hostage videos".
Mr Baker pinned the blame on the Remain campaign - which he said had descended "into insults, personal attacks and petty tabloid smears on key people".
He criticised Chancellor George Osborne's dismissal of the Brexit case as "economically illiterate" and cited the example of Lord Heseltine, who told the BBC he would be "very surprised" if Mr Johnson became prime minister after his "preposterous, obscene" remarks.
"I was appalled that such a distinguished figure as Lord Heseltine was used by Downing Street to attack Boris Johnson and convert the debate into one on personality not policy," said Mr Baker.
Another leading Leave campaigner, former cabinet minister Iain Duncan Smith, dismissed Lord Heseltine as "from the past" following his intervention.
Mr Baker claimed there had been "intolerable media smears" against leading Leave figures and their families, adding: "It is a dark day indeed when Conservatives believe that the centre is behind such vicious briefing."
He added: "If we're to come together after this referendum, personal nastiness must end now."
Speaking on BBC Radio 4's Today programme he said the Remain campaign "can't make an honest and positive case" because they "know it's a losing argument".
"So we've been reduced to fear, uncertainty and doubt on the Remain side, and lashing out at individuals," he said.
He added: "What essentially I'm saying is Queensberry Rules - so a full-frontal assault with due warning is fine - but the dagger in the heart inserted from the back through whispering in dark corridors is not OK."
A Downing Street spokesman said: "We don't accept Steve Baker's article.
"All our arguments are rooted in the thought that we are stronger, safer and better off in the EU."
The spokesman expressed confidence that the Conservative Party would be able to unite after the referendum.
Health Secretary Jeremy Hunt also said Mr Baker was wrong, and added: "Arguments have been made forcefully on both sides."
In other EU referendum news, former New York mayor Michael Bloomberg said a UK vote to leave the EU could hit UK-EU trade and leave British-based "employees worse off".
Writing in The Times, he warned financial jobs could leave London for Paris or Frankfurt and said "a vote to leave is a risk".


The fall-out from Nigeria's dramatic defeat to South Africa in an Africa Cup of Nations qualifier on Saturday looks set to continue after one player branded the absence of official match balls a "national disgrace".

Bafana Bafana won 2-0 in Uyo to record their first victory over the Super Eagles in a competitive match.
But the game was overshadowed by the use of footballs borrowed from the South African camp.
The Super Eagles turned up at the ground without balls approved by the Confederation of African Football (Caf) because the entire consignment of 250 sent to the Nigeria Football Federation (NFF) is still stuck at a port awaiting clearance.
Nigerian players had been training with footballs from their kit sponsors and only got a feel of the 2017 Caf balls during the pre-match warm-up.
To borrow match balls from your opponent is not only bizarre but embarrassing
"It's not the reason we lost but we trained with different balls only to use another ball for the game," said one player who requested anonymity.
Another player also speaking on condition he is not named said: "To borrow match balls from your opponent is not only bizarre but embarrassing."
NFF officials have not exactly been forthcoming either on the matter which left them with plenty of egg on their faces.
Back in January Caf sent 250 footballs to Nigeria for use during Champions League, Confederation Cup and international matches.
The balls were apparently sent to the wrong address and the NFF only just discovered the error when tracking the consignment.
"We are working on it now and remain confident that we will get the balls out before the weekend," an official told the BBC.
The NFF tried to use the 2016 match balls in Uyo but both the match commissioner and referee declined.


Plans to build 1,200 homes on the site of Deepcut Barracks in Surrey have gone on display.

The Army is due to leave the barracks in 2013, when training facilities will be moved elsewhere.
The exhibition is being held by Defence Infrastructure Organisation (DIO) as part of public consultation, Surrey Heath council said.
Proposals for the 117-hectare site include housing, open space, access roads, a primary school and some shops.
Opponents of the plan have questioned whether the infrastructure is adequate to cope with an influx of hundreds of new residents.
Surrey Heath council said this consultation was being carried out by DIO, which is responsible for Ministry of Defence (MoD) property, but the local authority would run its own consultation after a formal planning application was submitted.
The site is being released by the MoD following a national review of training that was prompted by the deaths of four soldiers in unclear circumstances at the Surrey army base.
Privates Sean Benton, Cheryl James, Geoff Gray and James Collinson all died from gunshot wounds between 1995 and 2002.
A coroner recorded a verdict of suicide for Pte Benton, but the inquests into the other three returned open verdicts.
The exhibition was taking place on Wednesday at Deepcut Village Hall.


Lancashire's Arron Lilley, Liam Livingstone and Jordan Clark have all signed new deals with the club.

All-rounder Lilley, 24, took his best figures of 5-23 in the win over Derbyshire earlier this season.
Batsman Livingstone, 22, hit a world record one-day score of 350 playing for Nantwich in April and has been a key part of the Red Rose's T20 side.
Clark, 24, was the first Englishman to hit six sixes in an over and the all-rounder has been a regular this year.
The lengths of the contracts have not been disclosed.
"It's great to have them on extended contracts," head coach and director of cricket Ashley Giles told BBC Radio Lancashire.
"They're the future of Lancashire cricket, so to retain their services for the foreseeable is great for the club."


A Chinese firm reportedly plans to ask its staff to seek approval before they get pregnant, provoking scorn in the state-run press and on social media.

Workers at a finance firm in Henan province were said to have been told they must apply for a "place on the birth-planning schedule" - and only if they had been employed for over a year.
Those who became pregnant without approval may be penalised.
The plan has been heavily criticised on social networks and in the media.
A commentator in the state-run China Youth Daily said the company regarded its workers as "tools on the production line" rather than human beings, the AFP news agency reports.
Employees are also unhappy, with one complaining that it was impossible to guarantee that a pregnancy would follow the schedule set by the company.
The firm,  in Jiaozuo, in the central province of Henan, has recently hired a lot of young women and is said to have been concerned that they would all go on maternity leave at the same time.
A representative of the firm admitted that it had circulated the plan to staff, according to news portal The Paper, quoted by the AFP news agency.
However, the representative reportedly said the plan was only a draft that was intended to invite comment from employees.
The plan distributed by the firm suggested that only married female workers who had been with the company for more than a year would be allowed to conceive - and only within a specific period.
"The employee must strictly stick to the birth plan once it is approved," the statement said.
Employees who became pregnant in violation of the plan, and in a way that affected their work, risked a fine of 1,000 yuan (Â£102; $161), the statement said. They may also have to forfeit year-end bonuses and promotion or awards.
Communist China enforces strict family planning policies, famously restricting couples to having only one child.


David Cameron is to tell voters they face a "stark choice" between him and Labour's Ed Miliband as the election campaign officially gets under way.

The PM will visit the Queen for a final audience ahead of the 7 May poll, marking the end of the five-year coalition government.
Later, he is expected to say the UK is on the "right track" and a Labour government would be "economic chaos".
Mr Miliband will say the Tories pose a "clear and present danger" to UK firms.
After months of unofficial campaigning, the five-and-a-half week race for No 10 begins in earnest.
Parliament is formally dissolved under the terms of the Fixed Term Parliaments Act.
Government ministers remain in charge of their departments until a new administration is formed but MPs will cease to be members of Parliament and writs will be issued for elections in all 650 constituencies.
Issues likely to dominate the campaign include the economy and spending cuts, Britain's EU membership and immigration.

After meeting the Queen at Buckingham Palace, Mr Cameron is expected to make a statement outside Downing Street in the afternoon.
It is understood he will say that "after five years of effort and sacrifice... this election is about moving forward".
What are the top issues for each political party at the 2015 general election?
Policy guide: Where the parties stand
He will say the "next prime minister walking through that door will be me or Ed Miliband" and a Conservative government would oversee "an economy that grows, that creates jobs, that generates the money to ensure a properly funded and improving NHS".
He will say Labour leader Mr Miliband "pays lip service to working people while planning to hike taxes and increase debt".
But setting out Labour's policies on business on Monday, Mr Miliband is expected to warn that the Tory promise of a referendum on Britain's EU membership poses a "clear and present danger" to jobs and prosperity.
It also risks an "extraordinary loss of British influence", he will say, as he promises to "return Britain to a leadership role" in Brussels under Labour.
Labour has said the economic recovery under the coalition has been the slowest in more than 100 years and resulted in a cost-of-living crisis.
It has pledged to raise living standards of "everyday working people by ensuring those with the broadest shoulders bear the greatest burden" while cutting the deficit and securing the future of the NHS.
Elsewhere, Deputy Prime Minister and Lib Dem leader Nick Clegg will have a separate private audience with the Queen on Monday in his capacity as Lord President of the Privy Council.
Campaigning in Oxfordshire on Sunday, Mr Clegg said leaving the EU would be an act of "self-harm" and risked the UK's economic recovery. It came as one of his senior colleagues, Energy Secretary Ed Davey, suggested the Conservative's commitment to an in-out EU referendum would make a second coalition with them "incredibly difficult".
On Sunday, the Conservatives accused Labour of planning tax rises to meet deficit reduction targets, while Labour said the Tories should "come clean" on "secret" plans for further welfare cuts.


A campaign to save a rare bandstand on the Dorset coast has won council backing.

The roof of Swanage's 96-year-old sunken bandstand was removed following storm damage in 2012.
The town's council agreed to put £50,000 towards the estimated £160,000 cost of its repair, if campaigners can match the amount.
Resident Alan Houghton said more than £30,000 had already been pledged and he was confident the rest could be raised.
He launched a campaign to save the bandstand earlier this year, claiming residents were "incensed" at its condition.
The venue, which is a rare example of a coastal bandstand sunk below ground, still regularly hosts performances, including by the town's brass band.
Mr Houghton said the council backing was "wonderful news" and an organisation was now in place and ready to start fundraising and preparing a bid for National Lottery funding.
In March, the town council set an ultimatum that the site would be filled in unless a realistic solution was found.
A council meeting on Monday agreed to contribute £50,000 of match-funding after "very positive" talks with the newly formed Friends of Swanage Bandstand.
Chairman of the council's tourism committee Caroline Finch, said: "The community spirit has been remarkable. It's clear there is a real nostalgia for the bandstand - it's a really special place.
"We are working with all parties concerned and I am, personally, very hopeful for a restoration of the bandstand."


Police investigating the rape of a man in Bolton have released further CCTV footage of a suspect they are looking for.

The victim, a vulnerable man in his 40s, was attacked in a car park just off Manchester Road in the early hours of Saturday 5 September.
His attacker is described as a white man in his 20s with short brown hair.
A 35-year-old man was previously arrested in connection with the rape, but later released without charge.
Greater Manchester Police have now released a second tranche of CCTV footage and urged witnesses to contact them.
Det Insp Damian Simpson said: "It is a month since this terrifying attack took place and, despite our extensive enquiries, we are still looking for the person responsible.
"We have released this new footage in the hope that somebody will recognise the man or at the very least it may jog someone's memory."


Five British candidates have made it through to the last 100 in the running for a one-way trip to Mars.

They'll now be tested to see how they'll cope on the red planet, before the final 40 are chosen.
Maggie Lieu, a 24-year-old from Coventry is one of the finalists.
"I'm overwhelmed with the excitement. Now that I've actually got there I'm even more determined to be the first person on Mars," she told Newsbeat.
The mission aims to send teams of four to the red planet every two years from 2025, until 40 people are living there.
The Dutch project is privately funded and needs to raise around Â£4bn to send up the first group. So far it's raised around Â£500,000 (so it's 1/8000th of the way there).
It's one of several projects aiming to put the first humans on Mars, but this one plans to let a reality TV show decide who goes and broadcast life on Mars.
"If we were to come back it would cost a lot more money.
"You'd have to transport a lot more fuel and there's nowhere to launch rockets from on Mars.
"There are also health risks with coming back to earth because the long term effects of the low gravity on Mars will affect our bone density and muscles.
"Astronauts who go to the International Space Station are pretty much disabled when they come back, they have to learn to walk again.
"It might be that our bones are so brittle, that just the impact of landing on earth would crush our bodies."
"It's true I'll never be able to see my family and friends ever again in person, but I'll be able to see their pictures, I'll still have access to the internet.
"I can write emails home and talk as humans do all over the world.
"That'll be good enough for me because the people I'd go to Mars with I'd have spent 10 years with.
"That's pretty much half my life so far so they'll pretty much be my new family and friends."
"At first they thought I was crazy and didn't really believe it was true.
"Now they're a little bit scared. Everyone keeps telling me "don't go getting selected".
"My mum still doesn't think it's real, she keeps joking with me saying: "When are you going to move out? When you go can I have all your money?"
"If I really did go I think my mum would be quite upset.
"She's only got one daughter, but I did go away to university for a whole year and it wasn't that bad because I called home every day."
"I do feel a little bit guilty because if I get selected I'll have the choice of whether to leave everything behind or not.
"That is kind of scary for me just having the choice.
"In some ways I think at least I've tried to go to Mars and if they don't select me at least I don't have to make the choice."
"That would be horrible.
"I won't be able to contact home or have any communications with earth, but hopefully we'd be able to repair it because we'll be trained up in every skill we need.
"We'll be trained electricians, doctors, plumbers, anything we need on earth."
"I'm very open to having a baby on Mars. I think it would be really exciting to be the mother of the first ever baby born there.
"My baby could be the first ever Martian, we'd be the Adam and Eve of Mars.
"But I'm also pretty aware there are a lot of risks involved because you don't know what the gravitational effects are."
"One-in-three missions to Mars fail, so it's pretty likely the rocket would explode before we got there.
"Then there's no technology at the moment to vent the oxygen on Mars.
"So if we're producing loads of oxygen we have to maintain it to a suitable level, similar to earth.
"If we make too much we'll cause a huge hazard of fire."
"On the International Space Station they wear disposable clothes because there's no washing machine.
"When we leave we'll have to wear special masked suits that are pressurised and suitable for the temperatures (-60C).
"We'll spend our lives in inflatable domes with a bedroom, a living room, a workspace and a plant room where we'll grow our food.
"When we get to Mars there will be showers. We'll produce our own water from the soil.
"But the journey there is anything between six and nine months and during that time there are no showers. There's only very limited water so we'll have to use wet wipes for six to nine months.  It's kind of gross."
"We're going to grow our own food so it's going to be pretty much a vegan diet. Lettuce has been experimented on and grown on Mars.
"Potentially we could be eating insects because they've got high protein so we could take an ant farm or something and eat ants. I don't really crave much."
"The project isn't fully funded yet. I think Mars One will definitely generate a lot of interest in humans going to Mars.
"Nasa and the European Space Agency have shown an interest in getting humans to go to Mars since this project started.
"So I think eventually someone will do it - whether it's Mars One is another question."
