There's no question that rookie trainer Kerry Lee's favourite day is Saturday.

Lee, who took over the reins of the 30-horse family training operation from her father Richard in July, has earned her growing reputation on the back of mopping up a string of valuable prizes on the highest-profile afternoon of the racing week.
In 2016 so far, Bishops Road ran away with a supposedly competitive race at Sandown on 2 January, a week before Mountainous ploughed through deep Chepstow mud for a second victory in the postponed Welsh Grand National.
Then on 16 January, it was the turn of the stable's runner Russe Blanc, jump racing's only white horse, to darken the mood of his rivals in a televised race at Warwick. Most recently, Top Gamble caused a shock result when defeating the reigning Queen Mother Champion Chaser Dodging Bullets at Newbury.
And the 39-year-old is not stopping there. Highlighted on the calendar at Lee HQ in west Herefordshire is the date of the most important Saturday of the jumps season, 9 April, when all eyes will be on Aintree for the Crabbies Grand National.
Bishops Road, Mountainous and Russe Blanc are all being targeted at the £1m prize - via, of course, more Saturday action.
"I'm like a kid the night before Christmas on a Friday night, I'm so excited," Lee told BBC Sport. "I can hardly sleep. It's amazing, it's what dreams are made of.
"People say that new trainers usually target smaller races, earlier in the week, but you've got to be a little bit bold, and that's the way I am.
"Basically, we are only a small yard, and I ride out and feed them, and hopefully know when they are in good health, and if I think it's the right thing to do, I'll do it."
In the run-up to Aintree, Bishops Road and Mountainous are likely to try to show off their big-race credentials in the three-and-a-half mile Betfred Grand National Trial at Haydock on 20 February; Russe Blanc, meanwhile, is set to travel to the North East for the Betfred Eider Chase, staged over four miles at Newcastle the following Saturday.
Lee said: "Bishops Road's owner Alan Halsall is a director of Aintree, so we bought him with the race in mind. He'll go up in distance at Haydock and that'll tell us if the Grand National or the [shorter] Topham Chase is best.
"Mountainous definitely goes to Aintree. People talk about him wanting very soft ground, but I think he's such a nice model of a horse, and a beautiful mover that any worries about better ground there will be cancelled out by the extreme distance.
"Russe Blanc really benefitted from being upped in distance at Warwick, and we hope that there's more to come from him, that's all I can say. He has the Irish National as an alternative."
The bad news on the Irish race, however, is that it's on a Monday.


Hearts came from two goals down to deny St Johnstone a 100% record in their post-split fixtures on a thrilling final day of the season at Tynecastle.

Saints led 2-0 inside 12 minutes after Liam Craig's opener from the penalty spot and a header from Graham Cummins.
But the hosts were level by the 21st minute, Arnaud Djoum looping a header in before Joe Shaughnessy's own goal.
Hearts had striker Abiola Dauda sent off for a lunge after 57 minutes, but held on as Saints threatened a winner.
Alim Ozturk denied Danny Swanson and Steven MacLean fired wide, before one final chance saw Tam Scobbie's header saved brilliantly by Hamilton.
But the visitors had to settle for remaining unbeaten in their final five matches.
They finished nine points adrift of Hearts in third, but both sides can take satisfaction from excellent seasons.
The Hearts players revealed a banner before kick-off thanking their fans for their "incredible" support during the season, and another full house of 16,046 were treated to a feast of early goals.
Hearts almost had the perfect start when Djoum found space on the edge of the 18-yard box but his shot was deflected wide for a corner.
Saints took the lead in the ninth minute when John Souttar tangled with Cummins in the box from a long throw-in.
Referee Greg Aitken pointed to the spot despite the hosts' protests and Craig fired the ball into the bottom right-hand corner.
Saints doubled their advantage three minutes later as the home defence again failed to cope with a set piece, Cummins meeting a corner from the left on the volley for his eighth goal of the season.
Hearts looked as if they were going to be overrun by Tommy Wright's hungry side but they bounced back quickly when Djoum sent a looping header beyond Alan Mannus into the top corner.
And Robbie Neilson's side were back on level terms four minutes later.
Prince Buaben sent in a cross aimed at top scorer Juanma, but Shaughnessy arrived first and sent a header over his own goalkeeper into the net.
Hearts' players now looked as if they believed in themselves and only the feet of Mannus denied Dauda the lead.
The recalled keeper then made a wonderful save from the same player moments late, diving low to his right to keep his goal intact.
Danny Swanson looked as if he had regained the lead for Saints with an angled shot from close range but a last-gasp clearance from Callum Paterson kept the sides level at the interval.
Saints striker Chris Kane missed a good chance when clean through on goal, clipping the ball over Jack Hamilton but also over the Hearts crossbar.
Challenges were flying in from both teams with referee Aitken struggling to keep control of affairs.
And the home side were reduced to 10 men when Dauda saw red for a thumping challenge on Craig, who was fortunate to avoid a card himself for his reaction.
Only Hamilton in the Hearts goal stood back as the other 21 players on the pitch joined the melee that followed.
Hearts continued to press forward despite being a man down and Alim Ozturk's free-kick brought another wonderful save from Mannus.
But after Ozturk denied Danny Swanson and MacLean fired wide, Saints had one final chance but Tam Scobbie's header was brilliantly saved by Hamilton.

Huddersfield extended their lead at the top of the Championship with victory in an even game at Ipswich thanks to Christopher Schindler's header.

The Terriers, who lost their previous two away games, hit the post through Elias Kachunga in the first half.
Schindler's downward header from Aaron Mooy's corner gave the visitors the lead after the break.
Ipswich's Grant Ward volleyed wide from a Leon Best flick-on but they have now won just two of their past 11 games.
Tom Lawrence sent a free-kick just wide for the hosts in the first half, but Mick McCarthy's side lacked a cutting edge in the final third.
Listen to Huddersfield boss David Wagner speaking to BBC Radio Leeds
They have failed to score in their past four Championship games and have scored just four goals in their past 10 league games since hitting four past Barnsley on the opening day.
Huddersfield's attacks mostly came on the counter and they were content to defend their lead in the second half, but Kachunga was very unlucky not to have opened the scoring earlier when his sweet strike struck the post.
The Terriers have won eight of their first 11 league games and are now 12 points ahead of McCarthy's Ipswich.
Huddersfield Town manager David Wagner:
"I am very surprised as the only teams who could have expected this start is Newcastle, Norwich and Aston Villa.
"But I am not surprised by how my players are working together and how fit they are. In football, it is all about the little details and getting these details right to win games.
"For any manager in the Championship, three points at Ipswich is huge. This is a very difficult place to come against an aggressive team but we stayed in the game and then got our goal."
Ipswich Town manager Mick McCarthy:
"We weren't very good on the ball and we didn't create anything. We have got some injuries but I expect more from the players I had out on the pitch.
"It is difficult at the moment. I am not surprised by the fans' reaction. We did not play as well as we could and the crowd are getting frustrated and venting their feelings.
"I am doing the job to the best of my ability but if we are not as good as the crowd think we should be, then they pay their money and it is up to them if they want to boo. I am not happy with how we played myself."

A South Korean man who was abducted by North Korea 41 years ago has managed to return home, officials in Seoul say.

Jeon Wook-pyo, now 68, was among 25 crewmen aboard two fishing boats captured by North Korea in the Yellow Sea in 1972.
He escaped North Korea in August and returned to South Korea this month, Yonhap news agency reported.
The North and South remain technically at war after the 1950-53 conflict ended in an armistice and not a peace treaty.
A spokesman from South Korea's Unification Ministry, which oversees affairs between the two Koreas, confirmed the man's return but did not offer additional details.
Mr Jeon made his way to South Korea via an undisclosed third country, from which he issued an appeal for help to South Korean President Park Geun-hye, Yonhap news agency said, citing an unidentified government official.
No information was given about the other crewmen on the boats.
Mr Jeon was currently under investigation in the South and would be allowed to return to his family after that was complete, the official was quoted by Yonhap as saying.
There is a great deal of suspicion surrounding South Koreans who return from the North, the BBC's Lucy Williamson reports from Seoul.
According to South Korea, about 500 of its citizens - most of them fishermen - have been abducted by North Korea since the Korean War.
Those kidnapped were often used for propaganda activities or intelligence gathering, Yonhap said.
One of the most well-known abduction cases involved a film director and his actress wife, who were abducted by North Korea in the late 1970s.
Late film director Shin Sang-ok and his wife, Choe Eun-hui, managed to escape in 1986 while attending a film festival in Vienna.
North Korea is also known to have abducted a number of foreign nationals, including several Japanese civilians in the 1970-80s to train spies.
In 2002, former Japanese Prime Minister Junichiro Koizumi managed to secure the release of five Japanese abductees.
Pyongyang says other known Japanese abductees are dead, but Japan is not convinced and wants more information. The issue remains a highly sensitive one between the two nations.


Bob Mortimer has cancelled the first leg of a UK tour with comedy partner Vic Reeves after undergoing a triple heart bypass operation.

Mortimer was due to take to the stage alongside Reeves in Glasgow next month as part of a 25th anniversary show.
Neil Reading, spokesman for Mortimer, 56, said he needed "several weeks" to recover from the operation.
Reeves said: "I'm so pleased the operation has gone well and Bob is fixed. Many thanks to the surgeon."
Their tour, 25 Years Of Reeves And Mortimer: The Poignant Moments, was due to start on 8 November.
Mr Reading said: "Bob would like to thank his consultant and all the nursing staff at the hospital for looking after him so well.
"He now needs several weeks to fully recover, so unfortunately the first leg of the UK tour will be cancelled.
"Bob very much hopes to be fit and well enough to perform the second leg in January next year."
The tour is expected to combine elements from TV shows like Shooting Stars and Vic Reeves Big Night Out, with characters such as Man With The Stick, The Stotts and Mulligan and O'Hare.
All ticket holders for performances from 8 November to 4 December are advised to contact their point of purchase for a refund.
It is hoped the January and February 2016 shows will go ahead as planned.
When the tour was announced earlier this year, Mortimer said: "Playing in front of a living audience is where it all began for us."
He added: "I will ensure that Vic arrives at all dates smartly dressed and unarmed. I promise not to mention football, JLS or apricots during the performances.
"Should you choose to attend, be warned - I will be not be wearing a toupee."
Fellow comedians and broadcasters have wished Mortimer well on Twitter, including Jack Dee, Charlie Higson and Sherlock actor and writer Mark Gatiss who said: "All love and luck @RealBobMortimer for a speedy recovery, pet."
Absolute Radio presenter Christian O'Connell said: "Get well soon @RealBobMortimer. The man's a true gent and been making me laugh for years."
Pointless star Richard Osman wrote: "The loveliest, funniest man you could ever hope to meet. Get well soon."
The heart is covered in blood vessels that feed it with oxygen and nutrients.
But fatty deposits - which are more common in smokers or overweight people - can clog up these arteries.
A heart bypass - official known as a coronary artery bypass graft - uses blood vessels from other parts of the body to rewire the heart's blood supply.
Arteries and veins from the the arm, chest and leg are used to bypass any blockages.
Some patients have only a single bypass, but it is more common for two, three (a triple heart bypass) or four grafts to be needed.
It is a common operation with around 20,000 taking place in England alone every year.


US carrier United Airlines grounded all of its flights for about two hours on Wednesday due to a technical issue.

United said it had suffered a "network connectivity" problem - the same issue that grounded its flights on 2 June.
The US aviation authority (FAA) said the airline resolved the issues at about 10:00 ET (14:00 GMT).
The company has suffered technical issues in the past, including one that meant first-class seats were sold in error for just $100 (Â£65) in February.
"We experienced a network connectivity issue this morning. We are working to resolve this and apologise to our customers for any inconvenience," United said in a statement.
The problem impacted as many as 3,500 flights, the airline told the CNBC TV news network.
United customers complained of delays and a lack of information on Twitter on Wednesday morning.
One passenger, Jeralyn Novak, tweeted: "Never flying @united ever again! The whole computer system is down and stuck in Boise."
Betsy Fischer Martin, a journalist travelling with United, tweeted: "Our @united airlines pilot on their global outage: "It's like someone pulled the plug on our computers - It's embarrassing, I apologise.""
United said it was "recovering" and "restoring flight ops" after the FAA order was lifted, but long queues were reported at airports across the US.
It was the latest in a series of technical problems that the US carrier has had in recent months.
Last month, United was again forced to ground its planes across the US due to an unspecified computer problem.
And in February, the company cancelled thousands of bookings after a computer glitch allowed transatlantic flights to be bought for very low prices.
United said it would not honour the fares as the error was caused by a "third party software provider" - provoking criticism from customers.
It is not the only airline to have suffered with technical issues though.
In April, rival US carrier American Airlines also had to ground its planes after a glitch caused iPad software - used by its pilots to view flight plans - to stop working.


Seven men have been arrested in raids at properties in Oxfordshire as part of an operation related to child sexual exploitation.

About 120 Thames Valley Police officers executed warrants at 10 properties in Banbury, as well as one in Birmingham.
The men were arrested on suspicion of rape and other offences relating to three females between 2008 and 2015.
Det Supt Paul Hayles called it a "complex investigation into non-recent child sexual exploitation" in the town.
He added: "Following the arrests we are continuing to work with our partners to safeguard and support the victims."
The raids on Tuesday morning are part of what the police are calling Operation Nautical.
The men arrested are aged between 21 and 42 and remain in custody.
Supt Kath Lowe, local police area commander for Banbury, said: "The nature of these arrests may appear concerning and I understand that people may have questions about them.
"Because this is an ongoing investigation, we will not be able to provide all the information straight away, but we will keep the community updated when we can."
There is an increased police presence in the area following the arrests.


Pop star Robbie Williams says he is no longer likely to "fall off the rails", having found contentment with his wife, Ayda Field, and two children.

The singer, who had a well-documented struggle with depression and substance abuse in his 30s, said having a family "focuses the mind".
"Before the kids and the wife, it [his career] wasn't just a job," he told Chris Evans' Radio 2 Breakfast Show.
"It was trying to fill in all the blanks that were in the soul.
"And that didn't make sense. I got to the top of the mountain and it was like, 'Ow, I'm still in pain'."
"Then the wife came, then the kids came, and now it all makes sense... because souls are depending on me.
"My wife depends on me, my kids depend on me. I haven't got the excuse to fall of the rails, to maybe not turn up to this interview, to watch what I'm saying.
"It's a blessing."
However, the singer, who announced his new album The Heavy Entertainment Show earlier this week, said he still faced self-esteem problems and depression on a regular basis.
"My brain idles at neuroses and worry and panic," he said.
"The run-up to this album has taken three years and I've written 75-plus songs.
"But every time I've been into the studio, it's been under the heavy weight of: 'You're coming back, you're doing an album, this had better be a hit, you're 42, you're fat, you're eyes are droopy, go and write a bigger chorus'.
"It's an uncomfortable place to be [but] it propels me forward," he added.
Williams met Turkish-American actress Ayda Field in 2006, and they married in 2010.
The couple  had their first daughter, Teddy, in 2012, followed by a son, Charlton, two years later. Williams attracted controversy at the time by live-tweeting the labour.
The star, who has been sober for almost a decade, said the couple still held parties at his home - but they mainly revolved around "quizzes".
However, he admitted he had fallen off one wagon recently, after trying to get in shape for his new tour.
"Months ago, I went on this diet and it worked but it's kind of extreme. I lost seven pounds in five days.
"And then, seven days in, I woke up one morning and I thought, 'That's odd, there's a polaroid image in my head with me and some grapes and some peanut butter. That's strange, 'cos that didn't happen.'
"The second day I woke up and I went to the loo and there were crumbs in the bath.
"The third night, I woke up at the fridge and I'd been night eating every night. I put on nine pounds in the middle of the night, without knowing.
"That being said, I'm looking after myself. I'm carb-less, sugar-less, fun-less.
"I'm in those clothes I used to wear in the 90s."

Adult video websites appear to be exploiting a YouTube loophole to host explicit material on the platform.

News site TorrentFreak found some sites had uploaded videos that did not show up on YouTube, but could be viewed on third-party websites.
The exploit allows a website to host its video library for free, using Google's server space and bandwidth.
YouTube told the BBC its policies "prohibit sexually explicit content like pornography".
Videos can be uploaded to YouTube under a "private" setting that prevents them from appearing publicly on the website or in search results. This setting also disables the embed function that usually lets videos be posted on other websites.
However, TorrentFreak reported that some websites had found a way to play secretly uploaded videos on their own external services, by streaming the raw data from googlevideo.com - a domain operated by Google.
The news site said it was not clear exactly how the websites were achieving this.
Hosting videos on YouTube secretly would let an adult video site keep its costs low, while earning money selling access to its videos.
One California-based adult film producer suggested that the loophole was also being used to host pirated adult content.
"Copyright infringers take advantage of a private-video-share setting," Dreamroom Productions told TorrentFreak.
"They upload and store videos, and freely use them on third party websites to earn profits."
The company said Google did take down infringing copies of its content when notified, but added that the process sometimes took up to three weeks.
"YouTube should be aware of this. They are allowing the situation to continue by not plugging this hole," the firm said.
A spokeswoman for YouTube said: "We have teams around the world that review flagged content, regardless of whether it is private, public or unlisted. Content that violates our policies is quickly removed."


Lewis Hamilton headed Mercedes team-mate Nico Rosberg and Ferrari's Sebastian Vettel in first practice at the Canadian Grand Prix.

The world champion was 0.331 seconds quicker than Rosberg, despite using a slower set of tyres than the German.
Rosberg was on the ultra-soft tyre with Hamilton and Vettel on the super-soft.
Red Bull's Max Verstappen was an impressive fourth on the soft tyre - the slowest available - as Felipe Massa crashed his Williams heavily.
The Brazilian lost control on the entry to Turn One, spinning on to the grass and smashing into the barriers, emblazoned with the name of F1's newest corporate sponsor, a popular beer brand.
Massa said he had lost the rear as soon as he closed the DRS overtaking aid, which reduces rear downforce to increase straight-line speed.
He was not the only driver to experience problems on the demanding Circuit Gilles Villeneuve, but he was the only one to crash.
Vettel brushed the wall exiting one of the chicanes, while Hamilton, Rosberg, Verstappen and Alonso all cut the final chicane when they misjudged their braking points.
There were also a couple of misunderstandings between drivers out on track, with Verstappen and McLaren's Fernando Alonso respectively incurring the wrath of Williams' Valtteri Bottas and Hamilton as they slowed for the final chicane while their rivals approached on a flying lap.
Both Bottas and Hamilton complained to their teams over the radio about the potential risk of the incidents.
Verstappen received a reprimand by the stewards for impeding the Williams after the session finished.
The only surprise in a somewhat low-key session - held in cool but dry conditions with drivers doing relatively few flying laps - was that Red Bull's Daniel Ricciardo did not set a representative quick time.
The Australian, who missed out on certain victories in the last two races in Spain and Monaco after team strategy and pit errors, was quick early on but did not improve his time as his team-mate did and ended up only 11th fastest.
At the front, Vettel was only 0.157secs slower than Rosberg and only 0.31secs quicker than Verstappen.
Ferrari's Kimi Raikkonen was fifth, ahead of Bottas, Force India's Nico Hulkenberg, Toro Rosso's Carlos Sainz, Force India's Sergio Perez and Alonso.

US Vice-President Mike Pence has said his country's "era of strategic patience" with North Korea is over.

Mr Pence first made the remarks at the demilitarised zone (DMZ), the area dividing the two Koreas, during a visit to South Korea to reaffirm ties.
His visit comes amid escalated tensions on the peninsula, with heated rhetoric from both North Korea and the US.
He arrived in Seoul on Sunday hours after North Korea carried out a failed missile launch.
On Monday, the US and South Korea launched a joint air force military exercise to ensure readiness against North Korea, according to South Korean media.
Mr Pence, whose father served in the Korean War, visited the truce village of Panmunjom, where the war's armistice was signed.
Speaking alongside South Korea's acting President Hwang Kyo-ahn later, he said North Korea had conducted nuclear and missile tests as the previous US administration had observed a policy of "strategic patience", but this was now over.
"Just in the past two weeks, the world witnessed the strength and resolve of our new president in actions taken in Syria and Afghanistan," Mr Pence said.
"North Korea would do well not to test his resolve or the strength of the armed forces of the United States in this region."
He reiterated US support for South Korea, telling his host: "We are with you 100%."
Mr Hwang hailed the early deployment of the controversial US missile defence system (known as Thaad) designed to protect against threats from North Korea.
The US vice-president said he was disappointed that China had taken retaliatory actions against South Korea in response to the move.
Mr Pence's latest comments echoed those made by Secretary of State Rex Tillerson, who warned that pre-emptive military action was "on the table" when he visited the DMZ last month.
Russia's Foreign Minister Sergei Lavrov said Moscow would not tolerate "missile adventures by Pyongyang" but a unilateral use of power by the US would be "a very risky course".
On Sunday, Lt Gen HR McMaster, the US top security adviser, said his country was working on a "range of options" with China, the first confirmation the two countries were co-operating to find a solution to the North Korean issue.
US President Donald Trump also said on Sunday that Beijing was "working with us on the North Korean problem". He had stated last week that the US and its allies may "deal with" Pyongyang if China did not.
The BBC's Stephen Evans in Seoul says US policy now seems to be to persuade China to contain North Korea while keeping the economic and military pressure on.
China, historically Pyongyang's sole major ally, has reiterated its call for North Korea to stop all tests, and has also called for a peaceful solution.
Chinese Foreign Ministry spokesman Lu Kang told reporters in Beijing on Monday that the Korean peninsula was "highly sensitive, complicated and high risk" and that all sides should "avoid taking provocative actions that pour oil on the fire".
He added that the crisis is between the US and North Korea, noting that "China is not the initiator of the Korean peninsula nuclear issue".
Besides Sunday's launch, North Korea has held a series of large-scale events in the past week including a massive celebration and military parade on Saturday.
Also on Monday, North Korean leader Kim Jong Un penned a letter to Syrian President Bashar al-Assad to mark the 70th anniversary of Syria's independence, according to state news agency KCNA.
"I express again a strong support and alliance to the Syrian government and its people for its work of justice, condemning the United States' recent violent invasive act against your country," he reportedly wrote.
Pyongyang has denounced the US deployment of an aircraft carrier group to the region, saying it would respond by "force of arms" to "reckless moves".
Observers have said North Korea may conduct a sixth nuclear test soon, with activity reported at nuclear facilities, according to the  website 38 North.
Meanwhile about 1,000 US airmen and fighter jets are taking part in a combat training exercise in South Korea, reported Yonhap news agency. South Korea has sent about 500 personnel and planes. The Max Thunder exercise will last for two weeks.
Mr Pence is visiting South Korea, Japan, Indonesia and Australia on a 10-day Asia tour.
He is expected to discuss rising tension on the Korean peninsula with Japanese Prime Minister Shinzo Abe on Tuesday, when he heads to Tokyo for economic talks with Finance Minister Taro Aso.
Mr Abe on Monday told a parliamentary session that diplomatic efforts were "important to maintain peace", but "dialogue for the sake of having dialogue is meaningless".
He added that Japan needed to apply pressure on Pyongyang to "seriously respond to a dialogue" with the international community.
What impact will S Korea's expanded missile defence system have?

A North Sea drilling contractor is set to make more than 100 people redundant.

Ensco said in a letter to employees that two rigs had been stacked in the shipyard as a result of current market conditions.
The memorandum said: "We are anticipating up to 117 redundancies.
"However, in order to minimise this number, we are implementing a recruitment and promotion freeze and seeking voluntary redundancy."
The rigs involved are the Ensco 70 and Ensco 102.


Gary Barlow says he'll sing at the weddings of three fans this year and has revealed he's already picked the first one.

"In 2015 I want to sing at 3 weddings," the Take That singer posted to his 3.7m followers.
He then followed that up with: "Ok we're 1 wedding down! Really looking forward to it."
The Take That singer says he receives "thousands of requests" to sing at people's weddings.
One person joked they were going to marry "another big GB fan" to double her odds of getting Barlow to her wedding.
Barlow said he would only pick "HUGE fans" who "stalk" him on Twitter.
He says he won't announce which weddings he's picked, but will organise it with the bride's best friend as long as they keep it secret.
"I won't publish on here which weddings till after the event."
In 2014 Barlow surprised a fan at her wedding after a year long twitter campaign by the maid of honour using #getgary2louswedding.
Barlow called it "the best use of Twitter".
The bride, Louise Newman, said: "It was just magical. I went up and cupped his face in my hands, then he got down on one knee and sang to me."
Her husband Mark said: "He just turned around and thought he was a really good lookalike then I realised he was actually singing the song and it was him.
"I saw a couple of tears in their eyes."

A body has been found in the search for a missing woman who vanished after a boat capsized on a river trip in Laos, south-east Asia.

Johanna Powell, from Cardiff, was reported missing on Saturday.
The 37-year-old, a BBC Wales picture editor, was on a tourist boat on the Mekong River near Pak Beng.
Her brother-in-law Dean Price said the family was told she was asleep when the boat hit a rock in rapids causing it to tip, take on water and capsize.
Ms Powell, originally from Pontypridd, was with three friends from Wales and one of them was celebrating a 40th birthday. They were part of a group of 10 on the boat, which could hold 25.
The Foreign and Commonwealth Office (FCO) has confirmed a body has been found but not yet identified.
The co-owner of the cruise company, Adisak Star, said the boat sank quickly after hitting a rock while travelling though rapids.
"The boat went down in a minute," said Mr Star, of Thailand-based Nagi of Mekong.
Mr Star said the other passengers managed to jump off the steel-bottomed boat, but it is not known what happened to Ms Powell.
One of the survivors ran across the roof of the boat until it sank and then swam to the rocks.
She described the water as "so rough - like a washing machine" and believes the conditions were why the boat sank.
"It was terrifying. We all thought we were going to die," she said.
Speaking to BBC Wales on Monday, Ms Powell's tearful father Donald said: "The boat hit some rapids apparently and overturned.
"Out of all the ones on board, the rest were lucky and they got to the bank somehow, but Johanna was missing.
"And we've heard today that they have found a body. They've not identified yet and we're just hoping it's not her."
Her mother Teresa said: "She got on the plane, she texted me and said 'It's going to be a lush adventure, mum. I love you loads and everything is going to be fine', because I was worried about her going."
Mr Star said cruises had been suspended following the accident and he could not say when they would resume.
He added the boat's captain owned the vessel and was experienced. Mr Star said the captain had been "detained" by local police in Luang Prabang.
Passengers on the trips are not obliged to wear lifejackets in normal conditions.
"We have been running this for 15 years now and this is the first time this happened and I am sorry this happened," Mr Star added.
Mr Star said water came in on one side of the boat so people moved to the other side and the boat turned over and split in two.
The company said it will review safety measures and the cruise industry will also investigate the accident.
The head of news at BBC Wales, Mark O'Callaghan said: "Jo has always been highly regarded by her colleagues at BBC Wales.
"We don't know exactly what happened, but this is extremely distressing news.
"Our thoughts are with her family, friends and work colleagues."


Euro 2016-bound Willie Collum should not be refereeing in the top-flight, according to former Hearts and Hibernian midfielder Michael Stewart.

The Scottish FA has declined to respond to the remarks, which follow a controversial penalty awarded during Aberdeen's 3-1 defeat in Inverness.
"It beggars belief how Willie Collum can still be refereeing at the top level of this game," said Stewart.
"There's just far too many of the big decisions he gets wrong."
Collum, who has been a Scottish top-flight referee since 2005, has Champions League experience and was in charge of last year's Uefa Super Cup final between Barcelona and Seville.
The 37-year-old has also been chosen as one of the 18 referees officiating at the Euro 2016 finals in France this summer.
However, Aberdeen manager Derek McInnes believes that Collum was "conned" by Caley Thistle's Ross Draper as the midfielder grimaced after he and Ash Taylor stretched for a loose ball inside the penalty box with the scores tied at 1-1.
Football pundit Stewart agreed and told BBC Scotland: "I think anybody who was watching that on the television could see instantly that, yes, the two feet were high, but there was no contact.
"Ross Draper fell down in an artificial manner because, if he'd been kicked, he would've spun the other way.

"It goes without saying that Ross Draper needs to be bearing some of the brunt of the criticism, but this isn't a case of a different referee every week - the recurring theme is that it's Willie Collum.
"This can't carry on. He completely and utterly ruined the game last night."
Aberdeen believed they should have been awarded penalties following later challenges on Graeme Shinnie and Taylor.
On the choice of Collum for top games in Scotland and in Europe, Stewart said: "It begs the question for me of - who is making these decisions?
"Ultimately, there has got to be a level of accountability here."
The SFA does not comment on individual referee performances. However, Collum's performances are marked at each game by referee observers.
"Everybody is going to make mistakes, we all accept that, but Willie Collum seems to get penalty kicks, big decisions regularly wrong," added Stewart.


Birmingham City ended a three-game goal drought with a comfortable win over Fulham which was sewn up by half-time.

Stephen Gleeson opened the scoring with a low 25-yard shot minutes before Paul Caddis's penalty three minutes later.
Jon Toral's shot made it 3-0 by the break, but Fulham's James Husband was then sent off for a second booking.
Alexander Kacaniklic gave Fulham hope but Clayton Donaldson and Viv Solomon-Otabor scored late goals for Blues either side of one for Ross McCormack.
The home side came into the game with two wins in their last three matches but were left standing by Birmingham's quicker start.
Both sides had chances to score before Jacques Maghoma set up Gleeson to net his third goal of the season from 25 yards.
Then, on 21 minutes, Caddis scored from the spot after the arm of keeper Joe Lewis brought down Donaldson.
Tim Ream went close for Fulham but that just spurred Birmingham to turn the screw and add a third.
Maghoma stretched to win a ball that looked to be going over the line and crossed for Toral to shoot high into the roof of the net.
Jamie O'Hara's free-kick against the bar was an encouraging sign for Fulham, but after Husband picked up two yellow cards in as many minutes just after the restart, Birmingham began coasting, only for Kacaniklic to capitalise on sloppy defending.
In a lively finish, Blues' top scorer Donaldson's fifth goal of the season looked to have made sure of victory.
McCormack pulled another back for Fulham courtesy of a lucky deflection, but there was still time for Blues' late substitute Solomon-Otabor to get on the scoresheet - his first goal in league football.
Fulham manager Kit Symons:
"It's very disappointing, I fancied us going into the game, being on decent form with two big wins, so I expected better today.
Media playback is not supported on this device
"We actually started the game okay, we had a few decent openings and then to concede two goals in such a short space of time is very poor defending from us.
"The third goal wasn't much better, and the sending off completely compounds it in the second half. At 10 men I thought we were quite brave and had a go.
"It was a fair red card, to be on a booking it was rash to go in like that, so I have no problems."
Birmingham manager Gary Rowett:

"I did ask them for a little bit more attacking quality today, and I felt we have been a bit wasteful in the final third, and not being ruthless enough.
"I didn't quite expect such a good performance today. We got into some brilliant positions, in the way we broke and kept our shape.
"Jon Toral was the best player on the pitch, in terms of his composure and his vision. We know what he's got - he's only 20 years old and starting games for the first time."


The death of a woman thought to have fallen from a balcony is no longer being treated as murder, police have said.

The 37-year-old's body was discovered off Canute Road, Southampton, on Monday afternoon.
A 61-year-old man from the city was arrested on suspicion of murder but has now been released without charge.
Hampshire Constabulary confirmed the woman's death was no longer being treated as suspicious.


Shimmering phenomena in the night sky - and starry sights billions of light years away - take a look at some of the finalists in the 2015 Insight Astronomy Photographer of the Year competition.

"Utterly enthralling with moments of brilliance" is how the comedian, impersonator and amateur astronomer Jon Culshaw describes the shortlisted entries in the competition to become the Astronomy Photographer of the Year.
With his personal interest in the cosmos, Culshaw was one of the judges this year.
He says he was aged about seven or eight when he got the space bug.
He looked for UFOs, was fascinated by lunar eclipses and always watched the Sky at Night.
We are joined in the circular Endeavour Room, with its domed ceiling at the top of the Royal Observatory in Greenwich, by another judge - Marek Kukula, the observatory's Public Astronomer.
"It is astonishing to see how far astrophotography has come in the past five years," he says.
The next image of the twinkling Milky Way was taken over a lake in the Pyrenees in south-west France.
Kukula says it is what the night sky would look like "if our eyes could take long exposure pictures like a camera".
"I love these noctilucent clouds which can be seen at certain times of the year, " says Culshaw of the next photo.
Normally seen in mid-summer in the UK - noctilucent clouds are high enough in the atmosphere to still be illuminated long after sunset.
"They are mesmorising," says Culshaw. "And taken over Sunderland, which is also pleasing."
Because the competition gets so many photographs of aurorae - the Northern and Southern Lights - there is a category just for them.
"It is a challenge to take an aurora shot which isn't a bit kitsch, a bit Christmas cardy" says Jon Culshaw.
But he describes the category winner as a wonderful shot with "the aurora cascading down, contrasted with a snowy mountainside cutting the image in two".
The next image took runner up in the Aurorae category.
"As a geeky physicist what I really like about this is the colours," says Kukula, "and how they are separated by height".
"It is to do with the physics of emitting atoms, high in the atmosphere. Green comes from oxygen, and the reds and blues come from a mix of oxygen and nitrogen. It is physics in action."
This next image - from the Our Moon category - shows the International Space Station crossing very close to the Terminator, the division between the illuminated and dark parts of the Moon, the lunar equivalent of day and night.
The moon is the largest satellite orbiting the Earth - the ISS is the second largest.
"The timing of this shot is great," says Culshaw. "And to get the detail of the space station - it doesn't look like just a blob or a fly on the lens."
"Unlike other astronomical objects - which emit too little light for photos - the Sun emits too much," says Kukula.
With the Sun he says, "photographers must limit the amount of light that comes into the camera - and this photographer has perfectly judged it with the right amount of dazzle".
The image is of the second diamond ring of the total solar eclipse of 20 March 2015.
Culshaw, who himself witnessed the eclipse from a ship just north of the Faroe Islands, says this photo makes him think of "clanging cymbals - an orchestral cacophony of light. It really does capture the drama".
Culshaw describes the next image as "a wonderful moment of serendipity".
It's called The Arrow Missed the Heart - and shows the Heart Nebula with Comet Jacques passing by.
Marek Kukula explains how near and far are juxtaposed beautifully here.
"The comet is well within our own Solar System - but the nebula is trillions and trillions of kilometres away."
Moving far, far beyond our own Solar System, the next photo is of a globular cluster of millions of ancient stars all swarming together like a cloud of bees.
"I would just love to be on the surface of a planet around one of the stars right at the centre," says Culshaw. "Imagine what kind of a night sky you would see. It would be incredible."
This next image is of colliding galaxies - "and for something so violent it's really rather graceful - like a dance," says Culshaw.
"It is a galactic crash playing out over millions of years," adds Kukula. "Red clouds of hydrogen - clouds of gas - collapsing to create new stars."
"This is a picture of the distant past and to see what the galaxies are doing now we will have to wait millions of years for the light to reach us."
This next image won the Galaxies category. It shows M33 - one of our neighbouring galaxies.
"You can see how chaotic the galaxy is with clouds of Space Dust," says Kukula. "Not a neat and tidy galaxy like the Milky Way or Andromeda."
Jon Culshaw says the People and Space category is one of his favourites.
"Part of the processing of this category is to reject certain images, where people have stood in what would otherwise been a lovely shot - as if to say LOL or take a selfie."
But in this next image he says, the interaction between people and space is very subtle.
He says the silhouetted figure adds a rather alien quality.
"I love the sense of the night sky being a cinema screen revealing a great display for the lone astrophotographer," says Kukula of the next image.
Taken in Chile, it shows the Milky Way arching in the night sky. The astronomer uses a red torch - so the red light won't affect his night vision.
This next image - taken in Hong Kong - won the People and Space category.
"It looks like rivers of molten quicksilver running down," says Culshaw.
But the photo was taken with a long exposure and the rivers are actually the torches of astronomers going up and down the hill.
"I love the fact that the winner of the People and Space category this year doesn't have any people in it!" adds Kukula.
The winner of the Young Astronomy section was taken by a 15-year-old boy, and features Comet Lovejoy.
Both judges describe it as technically very competent.
"Comet Lovejoy is still and vivid," says Culshaw, "in contrast with the dotty morse code star trails around it".
From the same category, this image of the total solar eclipse of 20 March 2015 was taken by a 7-year-old boy on a tablet computer, as he was on a flight over the North Atlantic.
"We were blown away by this," says Kukula. "He spotted an amazing sight and opportunity - and just clicked."
The next image took the special prize for robotic scope images. It shows an relatively close encounter between Comet Siding Spring and Mars.
Robotic scopes are sophisticated pieces of equipment - often powerful telescopes at dark-sky remote-site observatories. They are accessed by members of the public over the internet.
"It put me in mind of a 1970s science fiction special effect," says Culshaw. "I am glad there was no impact."
The Sir Patrick Moore Prize for Best Newcomer is for photographers who have only been taking images of the cosmos for up to a year.
It shows the Orion nebula - "a wonderful picture," says Culshaw.
"Like cigarette smoke in a club. Grey, blue and raspberry - contrasting shades beautifully captured."
This final image is the overall winner.
It is from the Skyscapes category and again it features the solar eclipse of 20 March 2015 - as seen from Svalbard, Norway.
Marek Kukula says it was a unanimous choice of the judges.
"It captures the moment of totality. The Moon blocking the Sun. The lighting effects in the sky reflecting in the snow. It feels like you are there."
Jon Culshaw says the image's beauty and power is in its simplicity - and it captures the feeling you get when you see an eclipse.
"A ball of rock the size of Australia blocking out the light of the Sun - but also the heat. There are huge laws of physics and the clockwork of the solar system being witnessed. I saw this and couldn't stop looking at it. It's almost other worldly."
Images from the Insight Astronomy Photographer of the Year 2015 competition can be seen at the Royal Observatory Greenwich in London until 26 June 2016.

Motherwell and Partick Thistle have expressed their anger at new Scottish Premiership fixtures and are demanding an amended schedule.

Thistle say that, if not, the two clubs and Hamilton would be due compensation for having fewer guaranteed games with Celtic and Rangers next season.
"That means an expected loss in revenues for the club of £120,000," Thistle suggested in a statement.
The Scottish Professional Football League has yet to comment.
Since the top flight was expanded to 12 clubs in 2013, the league has split into two sections of six teams for the final five fixtures.
"In previous seasons, where both Rangers and Celtic were in the Premiership, pre-split fixtures have been organised to ensure that every club plays three home games against the Old Firm," said Thistle.
"Without any notification from the SPFL to the contrary, we had expected that this practice would continue this season and that is the basis on which we and other clubs have budgeted.
"Having had no communication from the SPFL explaining these changes prior to this morning's announcement, Partick Thistle intends to seek compensation from the SPFL for all clubs concerned, or that they reconsider the fixture list to ensure a level playing field for all."
Thistle point out that Dundee, Hearts and Inverness Caledonian Thistle will have four home games each against the Old Firm before the split.
Expressing "anger and frustration", the Glasgow club say this will hand each of those clubs "an unexpected bonus" of around £120,000 each for the coming season.
Thistle, who had been looking forward to extra city derbies following Rangers' return to the top flight after a gap of four years, argue that this will also hamper them, Accies and Well in their quest for league points.
"Financial implications aside, we believe there is a significant sporting disadvantage created by the fixture list as it stands," they state.
"Pre-split, we will make four trips away to the two biggest clubs in the country while some clubs will only make two."
Thistle's statement was followed by Motherwell's board expressing its "extreme anger", saying it was a situation that had never occurred under the former Scottish Premier League or the present SPFL.
"This has a serious financial impact on our club and we cannot and will not accept it," they said.
"It creates a significant financial advantage for some clubs over others and, in our view, just as important, compromises the integrity of the competition, both in terms of the potential/need for adjusting respective player budgets up or down and the amount of games teams have to play at what has historically been the most challenging venues.
"We expect this unacceptable position to be reversed immediately."
Motherwell also complain that having two midweek matches in the Highlands away to Caley Thistle, three days after Christmas, and Ross County was also unfair on their fans.


A rare Ferrari racing car worth about £10m was given a parking ticket after the owners rolled it into a Mews to take some photos.

Historic car specialists Fiskens said they placed the car for a "short time" outside their Kensington headquarters when two traffic wardens approached.
The firm said the wardens were "adamant" the 45-year-old vehicle should be given a £120 fine.
Kensington and Chelsea Council said it was "issued as it would in any case".
Acquisition specialist Rory Henderson said the company were always "super-careful" not to obstruct others who use the Mews when moving their vehicles around.
A council spokesman said the photographer agreed to move the Ferrari but "no attempt was made" within the "statutory five-minute observation period".
The car, a 1970 Ferrari 512M, is still in working condition and was recently raced at the Le Mans Classic.
According to Fiskens, it has a "remarkable history" having been raced in the 1970 and 1971 Le Mans races.
In 1977, it set a new record after Robert Horne drove the car 192mph over a flying mile.
Fiskens call it "a superb example of one of Maranello's finest sports competition cars".


Tributes have been paid to a TT rider and Senior Manx Grand Prix winner who died on Saturday after a practice race crash on the Isle of Man.

Manxman Gary Carswell, 45, crashed his Honda Fireblade in the opening practice session of the Jurby Motodrome racing meet and was fatally injured.
Mr Carswell, who worked for Manx Utilities, died at Noble's hospital.
Fellow competitor and close friend Paul Duckett said he "loved everything about life and approached it with open arms".
An investigation into the crash has been launched, said the Andreas Racing Association, which passed on its sincere condolences to Mr Carswell's family and friends.
Mr Duckett said his friend was one of the best people you could ever come across, and somebody who would always try to help you.
"He took everything on with open arms and will be sadly missed," Mr Duckett said.
Manx Radio Sport commentator Dave Christian, who knew Mr Carswell for 35 years, said he was an "incredibly likeable and chirpy character who lived for his motorcycle racing - the world is a much poorer place without him."
He finished third in the 2004 Senior TT and won the 1997 Senior Manx Grand Prix.


A 24-year-old has been charged with the murder of man who died in hospital after being found with stab wounds.

Reece Allen, also 24, was discovered with multiple wounds outside an address in West Avenue, North Shields, in the early hours of Monday.
Police said Joe Welsh, of no fixed address, would appear in court later charged with his murder.
A 20-year-old woman who was also arrested has been released with no further action.


Wall Street stock markets hit a fresh record on Wednesday, with the Dow Jones Industrial Average ending above 20,000 points for the first time.

The S&P 500 and tech-heavy Nasdaq also achieved new highs, fuelled by hopes that President Donald Trump's policies will boost the US economy.
The Dow, which has nudged the 20,000 milestone during January, rose 0.8% to 20,068.51.
Investors' cash has poured into shares on hopes of tax cuts and higher growth.
The Dow had risen above 20,000 early into the trading day, prompting Mr Trump's senior adviser Kellyanne Conway to tweet that the landmark was down to "The Trump Effect".
"It was definitely a milestone that the market has been focused on for really the better part of two months and you were starting to get a little bit of anxiety as to whether it was going to be surmounted or not," said Julian Emanuel, Equity Strategist at UBS.
The Dow reached its latest 1,000-point milestone two months after closing above 19,000, making it the second quickest 1,000 point rise ever.
The index rose from 10,000 to 11,000 in only 24 trading days between 29 March and 3 May, 1999, while the rise from 18,000 to 19,000 took 483 trading days (nearly two years).
Financial stocks have been a major factor in the gain - with Goldman Sachs and JPMorgan accounting for around 20% of the rise.
This is because investors believe that some of Mr Trump's policies will trigger inflation and produce a rise in interest rates.
Also on Wednesday, the broad-based S&P finished up 0.8% at 2,298.37, while the Nasdaq advanced 1% to 5,656.34 - both fresh records.
Finally, the Dow hit 20,000 at the US market open after being tantalisingly close for weeks.
When the moment came, floor traders at the New York Stock Exchange were ready.
Long before the opening bell rang, one trader yelled 'get your hats on, get your hats on'.
He was referring to the baseball caps emblazoned with Dow 20,000 on the front.
It's a tradition dating back to the first time the Dow passed 10,000. To mark the occasion, they made hats. And the habit stuck.
Wall Street veteran Art Cashin, director of floor operations at UBS had his on.
When asked if the Dow at 20,000 matters, he answered that the publicity would make people think about their own investments and that was a good thing.
For many though today's historic milestone is just a round number. Its value is symbolic.
In part that has to do with the index itself.
The Dow Jones Industrial Average is made up of only 30 companies compared with 500 in the S&P 500. So it is far from comprehensive.
Then there is the way it is calculated.
The Dow puts too much emphasis on share price, unlike the S&P 500 which reflect its members market capitalization. As a result, a few names have the power to significantly move the index.
Make no mistake though, this will be front page news. And for market professionals, it's a moment to pop the champagne, celebrate and pull out their Dow 20,000 baseball caps because who knows when they'll be able to wear it again.
Tim Ghriskey, chief investment officer of financial management firm Solaris Group in New York, said: "There is a real belief that [Mr] Trump is real, he has been extremely active these first couple of days of the presidency and a change may happen faster than people had thought."
Neil Wilson, senior market analyst at London brokers Capital, said: "It's psychologically huge and, after a bit of pullback ahead of the inauguration, really confirms that the 'great rotation' from bonds to stocks is definitely upon us.
"Fears about protectionism are running second to optimism about inflation and growth - for now at least.
"The question now is how long can this last?
"Mr Trump's first steps as president have confirmed much of what investors had hoped for and that he's extremely pro-business and light on regulation for energy and financials. That's what's driving this renewed rally.
"The other argument claims that this is a massive bubble and if this is a real rotation from bonds into stocks, ending a 30-year bond bull market, there is still a huge amount of cash piled up that could yet pour into equities and power further gains through 2017.
"It might not be too long before 21,000 is in sight."


Take a look at this newborn Humboldt Penguin.

17 June 2015 Last updated at 14:31 BST
It's the second chick from mum, Cora and dad, Bigglesworth who is now 23 and the oldest penguin at Chessington.
He's been keeping a constant watch to try to protect the nest.
The colony of penguins moved into a new enclosure in March.
Keeper Nick Tulley said: ''The transition into the new enclosure was so smooth and the penguin couples all settled back into their original nests.
It is rare to see a successful birth happen so quickly.''


The myth that tennis player Andy Murray is labelled British when he wins and Scottish when he loses is wrong, a linguistics study has claimed.

Ben Dickson, from Stirling University, analysed UK press reports of Murray's Wimbledon matches from 2005-2014.
His study found that the press were "consistent" when describing his national identity, whatever the result.
How the Scotsman was labelled depended more on the type of newspaper and where it was published, Mr Dickson said.
The dissertation, on the use of national identity in sports reporting, formed part of Mr Dickson's MSc in applied linguistics. He examined about 200 press reports before coming to his conclusion.
The postgraduate student found that Scottish newspapers referred to Murray as Scottish twice as frequently as they referred to him as British.
In the UK national press, broadsheets tended to refer to Murray as Scottish, while the tabloids called him British.
But none of the descriptions tended to change with the result of the matches.
Tennis fan Mr Dickson said: "I was determined to put this issue to bed once and for all. My research shows that the result of Andy Murray's matches does not affect the way the UK-based press refer to his national identity.
"What has been identified, however, is that nationalism is key to the language of sports reports in the UK."
The student's research found broadsheets tended to give a voice to Murray only when he was successful and that tabloids tended to use more personal language like first names and nicknames.
Nationalistic terms were used to refer to Murray's opponents in all newspapers except one broadsheet.
Dr Vander Viana, who supervised the study, said: "The analysis of language constantly throws up surprises. Our intuitions on how we think we use language and how we actually use it are not the same, as this fascinating corpus research shows.
"Dickson's study dispels a long-standing myth on the basis of a thorough linguistic analysis."


Pakistan has carried out two executions, the first since a death penalty moratorium was lifted after a deadly attack on a Peshawar school.

One of those executed was convicted over an attack on Pakistan's Army HQ in 2009, the other over an assassination attempt on ex-leader Pervez Musharraf.
The UN had earlier urged Pakistan not to resume its executions.
Some 141 people, all but nine of them children, died in the Taliban attack on the Army Public school in Peshawar.
Pakistan's military carried out operations against Taliban units in areas near the border with Afghanistan on Friday, saying it had killed 59 militants.
The two executions were carried out in the central city of Faisalabad late on Friday, officials said.
Pakistani media named the two executed men as Aqeel, alias Dr Usman, and Arshad Mehmood.
Usman was arrested during the raid on the Rawalpindi HQ and sentenced to death in 2011.
Mehmood was sentenced to death over the attempt on Mr Musharraf's life in the same city in 2003.
The home minister for Punjab province, Shuja Khanzada, told Associated Press: "Today's executions of terrorists will boost the morale of the nation, and we are planning to hang more terrorists next week."
The Pakistani army chief has so far reportedly signed the death warrants of six terrorism convicts.
UN human rights spokesman Rupert Colville had earlier urged Pakistan not to resume executions.
He said: "To its great credit, Pakistan has maintained a de facto moratorium on the death penalty since 2008," he said, adding that those at risk of imminent execution were unconnected to the "premeditated slaughter" in Peshawar.
"We urge the government not to succumb to widespread calls for revenge, not least because those at most risk of execution in the coming days are people convicted of different crimes."
The human rights organisation Reprieve warned that innocent people could be executed as a result of the government's decision, accusing the authorities of routinely overusing anti-terrorism laws to secure convictions.
It said Pakistan had the world's largest number of death-row inmates - with more than 8,000 people awaiting execution.
Prime Minister Nawaz Sharif lifted the moratorium on executions in terror cases amid outrage at the massacre of the children.
The country's de facto foreign minister, Sartaj Aziz, said the Peshawar attack was his country's own "mini 9/11" and required a sea-change in its fight against terrorism.
Special classes were held in Pakistan on Friday in which schoolchildren chanted prayers in memory of the victims of the massacre.
The Taliban said that the attack was an act of revenge for its own losses in the army's military offensive.


US stock index provider MSCI has agreed to include China's mainland domestic shares in its emerging markets index for the first time.

The move is a step forward for Beijing as it attempts to open up its financial markets and attract foreign capital.
China's inclusion had been rejected for the past three years, amid worries about regulation and accessibility for global investors.
MSCI is world's biggest stock index provider.
The shares of 222 Chinese companies, known as A-shares, will be added to the Emerging Markets Index, though they will make up barely 0.7% of the index's value.
Karishma Vaswani: China's MSCI inclusion is a game changer
The MSCI Emerging Market Index currently has about $1.6 trillion tracking it.
This means those investors (mainly investment funds) will be obliged to have part of their investment in the A-shares of selected Chinese firms.
China's inclusion will have needed to support of many of these key investors.
The fact they've given the nod indicates they now feel the way Chinese markets are run and regulated has sufficiently improved.
"We view this announcement as an important milestone in the integration of China's equity markets with the rest of the world," said Jonathan Garner, chief Asia and emerging-market strategist at Morgan Stanley.
Far from it. There are already several ways to invest directly in Chinese firms.
Many Chinese companies have a dual listing, meaning they appear on both the Shanghai and Hong Kong markets. The Bank of China is one high-profile example.
And you find Chinese firms listed on some foreign markets. US-traded Chinese businesses include the e-commerce giant Alibaba.
And since late last year, foreign investors in Hong Kong have been able to trade shares in about 900 firms in companies on the Shenzhen Stock Exchange and vice-versa following the official launch of the Shenzhen-Hong Kong trading link.
That link followed the launch of the Shanghai-Hong Kong Stock Connect in November 2014, which allowed international investors to trade in hundreds of Shanghai-listed A-shares as well as Hong Kong stocks.
China has the world's second biggest stock market and third biggest bond market.
However, less than 2% of Chinese shares and bonds are held by foreigners.
The Shanghai and Shenzhen initiatives mentioned above are one way Beijing has tried to make its markets more accessible to foreign money and, crucially, to build trust.
The schemes had been "a pivotal part " in the MSCI inclusion said HSBC's head of Asia Pacific equities, Rakesh Patel.
There are confidence issues China has had to overcome - and there is still a long way to go.
The boom-and-bust nature of the markets over the past few years, with some high-profile crashes, has not helped the market's image.
Nor has the ad hoc, and often heavy handed, government intervention.
And there has also been the issue of individual stocks being suspended, often for long periods of time - though the frequency of this has been reduced said HSBCs Mr Patel.
"China has been given a big tick in the box from the international investment community and the MSCI," according to Sean Taylor, Asia Pacific chief investment officer at Deutsche Asset Management.
"And it might mean that over the next few years, they will accelerate reforms. It gives them the confidence to know that they are doing the right thing.
Ken Jarrett, president of the American Chamber of Commerce in Shanghai, said Tuesday's decision must be a catalyst for more change.
"We hope that the MSCI decision will spur domestic regulators to bring China's stock markets in line with global norms and make the regulatory environment more predictable, improve transparency in the stock market listing process, and bring stronger rule of law to the wider securities industry.
"This would mean not banning major stockholders from selling shares during periods of market turbulence, not suspending the trading of stocks outside the use of predetermined circuit breakers, and therefore not creating the conditions that lead to moral hazard."
Probably not for now.
China's stock market is worth about $6.9 trillion dollars.
And given Chinese shares will make up such a small part of the MSCI Emerging Market index there's a limit to how much foreign money will be attracted in.
Also, while the go-ahead has been given, its inclusion will not begin until May 2018.
"There is unlikely to be a significantly positive impact on A share index performance near term," said Morgan Stanley's Mr Garner.


Prince Ali bin al-Hussein of Jordan has announced that he will stand in the upcoming Fifa presidential election.

Ali, 39, pushed incumbent president Sepp Blatter to a second round of voting in May's poll, winning 73 votes, before standing aside in the contest.
He joins Uefa president Michel Platini as confirmed candidates to replace Blatter and lead football's world governing body.
The election is due to be held on 26 February next year.
"This election should be about football, not personal ambition. We have come too far to walk away now," Ali said.
"We must overcome deep-seated corruption but I was not brought up to walk away from a tough fight. This is about right and wrong."
Blatter, 79, triggered next year's election by announcing shortly after winning the last vote that he would resign amid twin criminal investigations into alleged corruption at Fifa.
Seven Fifa officials were arrested in May on charges of racketeering, wire fraud and money laundering.
Former Fifa executive Chung Mong-joon of South Korea has also indicated that he will run in next year's election, as has Liberian FA president Musa Bility.
Referring to May's election, Ali added: "I was the only person who dared to challenge Blatter, I ran because I believe that Fifa needs change.
"I had the courage when others feared. They didn't have the guts to run, but I did."


Christmas has come early for one husband this year after his son discovered his lost wedding ring in a box of tree decorations.

Simon Mills, 34, of Llanelli, Carmarthenshire, was left mystified when his gold band disappeared from his finger last New Year's Eve.
The family searched their home, car and gym and thought it was "gone forever".
But son Osian, five, spotted something shiny in the Christmas decorations this year and shouted: "That's Dad's ring."
Mr Mills believes he lost the ring after he lost 4st (25kg) in weight by getting fit to become a rugby referee.
Speaking of the discovery, he said: "It was amazing. I thought the ring was gone forever after all this time.
"We couldn't find it anywhere until Osian suddenly pulled out of the box holding the Christmas decorations.
"Then I remembered it was New Year's Eve last year when we had taken the Christmas tree down early. It must have slipped off then."
His wife Donna, 33, who had planned to buy him a replacement ring for Christmas, added: "We were all around the Christmas tree screaming - we never thought we would see it again."


Ian Cathro has agreed in principle to join Newcastle United as assistant manager to Steve McClaren.

Final negotiations are taking place with the 28-year-old Scot.
Cathro recently left Valencia for family reasons after moving to Spain with coach Nuno Espírito Santo from Portuguese club Rio Ave last year.
New Newcastle boss McClaren has said he wants his coaching team in place before the players return for pre-season training on 1 July.
After an injury-curtailed spell playing youth football, Cathro set up a coaching school in Dundee while he was still in his teens.
He then worked with Dundee United's youth academy for four years until 2011.
His move to Portugal came after a spell working for the Scottish Football Association's regional coaching set-up.
Cathro and Santo met while both were working on their coaching qualifications under the SFA and the pair led Rio Ave to a sixth-place league finish, two cup finals and European qualification for the first time.
Last season, they helped return La Liga club Valencia to the Champions League.
Cathro was recently linked with Rangers before the appointment of Mark Warburton as manager with David Weir as his assistant.


The campaign to save Van Dyck's self-portrait for the nation has received a boost, after the billionaire art collector buying it agreed to withdraw.

Financier James Stunt - the son-in-law of Formula 1 boss Bernie Ecclestone - decided to step aside after witnessing "the people's passion" to keep the painting in the UK.
The painting has now been offered to the National Portrait Gallery for £10m, down from the original price of £12.5m.
So far the campaign has raised £3.6m.
The National Portrait Gallery and the Art Fund launched the Save Van Dyck campaign in November. Since then it has received donations from more than 8,000 members of the public.
'When I agreed to buy this great portrait I didn't expect the huge swell of public opinion and the strength of emotion its export would generate," said Stunt, who had planned to hang the portrait in his Los Angeles home.
He added that he had "carefully reconsidered" his position and hoped that his withdrawal, together with the reduced price, would see the appeal succeed.
The appeal now has four months to raise the remaining £6.4m, before the deadline of 20 July.
Flemish artist Van Dyck came to work in England in 1632 at the invitation of King Charles I.
This painting, which dates back to 1640 - shortly before the artist died - has been described as "one of the finest and most important self-portraits" in British art.
The price was reduced following discussions with Stunt, current owner Alfred Bader and art dealer Philip Mould, who were impressed by the public support to keep the painting in the UK.
A joint statement from the Art Fund and National Portrait Gallery called it a "significant boost", which gave them "an improved chance of ensuring that the portrait remains on public display forever".
The work was in a private collection for almost 400 years before it was sold at auction in 2009.
It is believed to have been sold again in the interim.
When Stunt announced his intention to buy the painting, the Government issued a temporary export bar allowing campaigners time to try and save it for the nation.
The application process for an export licence has now been halted.
"Watching the public reaction to Van Dyck's self-portrait develop in this unprecedented way has been amazing, and, for this lover of British historical portraiture, reassuring," said dealer Mould.
"The picture has become an iconic focal point, and for many the thought of it going to the United States would be like losing a chunk of Stonehenge."
Currently on show at the National Portrait Gallery, the painting will embark on a three-year of the UK tour if it is saved.


The Gambia's President-elect Adama Barrow is to remain in Senegal until his planned inauguration on Thursday, state media in Senegal say.

The move was requested by West African leaders after a summit in Mali, Senegalese news agency APS said.
President Yahya Jammeh is currently refusing to step down until the supreme court can hear his challenge in May.
Regional bloc Ecowas wants the UN to approve military action if Mr Barrow's inauguration is blocked.
On Saturday leaders repeated their calls for Mr Jammeh - who initially accepted the result - to go voluntarily at an Africa-France summit in Bamako.
Mali's president Ibrahim Keita called for "proverbial African wisdom" to prevail to avert a bloodbath and there are growing fears that the uncertainty could cause a refugee exodus.
Thousands of Gambians, mostly women and children, have already crossed the border into neighbouring Senegal and further afield to Guinea-Bissau, where they do not require a visa, officials say.
Mr Barrow, who beat Mr Jammeh in last month's election, was at the Bamako summit and was referred to as the president.
Last week Nigeria's president flew to the Gambian capital Banjul to try to broker a deal but Mr Jammeh would not relinquish power.
Mr Jammeh's attempt to overturn the election result has been delayed because of a shortage of judges but his legal team has asked for an injunction to block Mr Barrow's inauguration.
The African Union has said it will no longer recognise Mr Jammeh's rule after his term ends.
The 51-year-old leader seized power in the country in 1994 and has been accused of human rights abuses, although he has held regular elections.


West Bromwich Albion have parted company with Pepe Mel after four months as the Premier League club's manager.

The 51-year-old Spaniard won just three of his 17 matches in charge as West Brom finished 17th, three points above the relegation zone.
Sporting and technical director Richard Garlick said the decision took into account events "on and off the field".

The West Midlands club were 14th when Mel signed an 18-month contract to succeed Steve Clarke in January.
Mel admitted on 9 May his future was in doubt, saying: "I'll meet with the chairman and see if the vision he has for the club is the same as mine."
The club then suffered a 2-1 home defeat by Stoke on Sunday to round off what Garlick described as a "very disappointing campaign".
He added: "Both Pepe and the club set out with the best intentions of making the appointment work. However, having reflected on events both on and off the field during our talks today, it became apparent that it was in the best interests of both parties for there to be an amicable parting.
"We are grateful for the manner in which the existing coaching staff and players have rallied behind Pepe to get the club over the line in what has proved an extremely competitive division."
West Brom said Mel had signed an 18-month deal when he arrived but the ex-Real Betis coach later claimed his contract was for only six months.
Mel's tenure at West Brom was marred by high-profile controversies off the pitch and largely poor performances on it.
The club sacked striker Nicolas Anelka on 14 March after the Frenchman announced via Twitter he was quitting The Hawthorns. Anelka, 35, had been fined and suspended for five matches following his 'quenelle' goal celebration.
Mel also had to address the aftermath of a dressing room altercation between team-mates Saido Berahino and James Morrison after the 3-3 draw against Cardiff.
Cardiff had snatched a stoppage-time equaliser in the match between the two relegation rivals on 29 March.
Two weeks later, West Brom surrendered a three-goal lead to draw by the same scoreline at home to Tottenham.
West Brom have also parted company with David Gomez, a Spaniard who was added to the coaching staff at Mel's request in February.
Assistant head coach Keith Downing and goalkeeper coach Dean Kiely will remain in their current roles while the club searches for a new boss.
Garlick added: "Although we have managed to achieve a fifth successive season of Premier League football, it has been a very disappointing campaign and lessons have been learned.
"The search for a new head coach has now begun. We aim to find the most suitable candidate who, with the support of the structure we have had in place for six years and are presently strengthening, will enable the club to be more competitive next season."


Ever wondered why it takes an age for some web pages to load on your mobile phone, even when you have a good signal?

It's because you're not just downloading the content you want - which may be a small amount of data - but the data-heavy adverts and all the tracking technology that surrounds them. And it's costing mobile users, who are charged for that traffic to their phones, a lot of money.
That, at least, is the allegation in an advert placed in the Financial Times this morning by an Israeli firm called Shine. Under the stark headline: "Fact: mobile ads consume a substantial amount of the data mobile consumers pay for and it's getting worse", it argues that we are all helping to subsidise advertisers.
It goes on to call on the GSMA, the trade association for the mobile industry, to back a move to "zero rate" ads, meaning consumers would not be charged for that data. Shine is a business which is trying to sell ad-blocking software to mobile networks, so it is not a neutral observer.
"We believe that consumers should not be subsidising billion dollar ad tech businesses," Shine's Roi Carthy tells me. "We hope the GSMA and its membership see the importance of protecting consumers and act on the matter swiftly."
The GSMA says that it cannot comment on commercial negotiations involving operators but says it supports "initiatives that provide consumers with more transparency and control over the privacy of their personal data".
Ad-blocking has grown increasingly popular, with plenty of tools now available to improve your browsing experience. A recent survey showed nearly 200 million people were using blockers - that's still a small proportion of the global web audience but 12 million of them are in the UK, which indicates that the British are  particularly hostile to adverts.
Up until now, it has been much harder to block adverts on mobile phones, but this week Apple is expected to release its latest mobile operating system which will allow ad-blocking tools in its Safari browser. That should give a big boost to businesses which will be marketing their ad-blocking services to iPhone users, and even to Shine, which is trying to persuade mobile operators to install its technology at the network level.
This sounds like a great consumer cause - until you remember that the entire business model of many of the web businesses we use most is dependent on advertising. When you check the weather forecast online, watch a music video or chat about recipes on a cookery forum, the chances are that you get those services free in exchange for having those annoying adverts.
No wonder there is something akin to panic in the online advertising industry, especially among businesses which are just getting their mobile ad strategies off the ground. What makes it worse for them is that Facebook, which has made a very successful transition to mobile, won't see its ads blocked because it controls its app platform. That means that everyone else could soon be shutting up shop as their ad revenues evaporate.
But perhaps we should take the warnings of the catastrophic impact of ad-blocking with a pinch of salt. The advertising industry is nothing if not ingenious and will come up with new ways of reaching consumers - ideas like the branded content pioneered on sites like Buzzfeed.
And, if the pain of waiting while another advert loads on the web article you want to read, persuades more of us to resort to blockers, the advertising industry will learn a valuable lesson. After all, annoying your customers so much that they want you out of their lives does not sound like a great marketing strategy.


A new food delivery business is trying to persuade more restaurants to embrace takeaway, by offering them the whole service on a plate.

"Two minutes to get to Nando's," says experienced cycle courier Rafal.
After a brisk ride through Islington in London, he tethers his steed, an electric bike, to a lamp-post outside the branch of the popular chicken eaterie.
After a brief absence, Rafal emerges with a box, consults a map on his smartphone, then rides for one minute to an address just around the corner.
A buzz on the intercom, and he disappears into the flat with his consignment of food.
Now you might be thinking, but Nando's doesn't deliver? You are right. That's where Rafal's employer comes in, a company called Deliveroo.
Street food
"I used to work in New York in investment banking," explains Deliveroo's founder Will Shu.
The 35-year-old is sitting in the metallic confines of Dishoom, a trendy London restaurant specialising in contemporary Bombay street food, which has signed up to Deliveroo.
"[At the investment bank] we had to order food in late at night all the time, and the options were very good. But when I moved to London in 2004, I found there to be a lack of quality takeaway.
"This idea [for Deliveroo] just stuck in my head for a long time, until I founded the company in 2012."
Like most other aspects of modern life, the food delivery business has been shaken up (or "disrupted" to use the current business buzzword) by internet technology.
In recent years online food delivery companies like Hungryhouse and JustEat have both established themselves as successful businesses in the UK.
"[But these] are what we call online marketplaces," says Mr Shu, "meaning they are not involved in the delivery of the food itself."
Firms such as JustEat sign up restaurants that already offer takeaway, then operate as an online hub, on which hungry members of the public can place their orders. Deliveroo goes one stage further, by also doing the delivery work for the restaurants.
"In our platform, all restaurants have to do is cook the food, and we take it and bring it to people, which means we can work with a higher class of restaurant."
On your bike
Back to Rafal, who is one of Deliveroo's most experienced cyclists.
A self-confessed cycle nut from Poland, he has just returned from a one-month trip pedalling around France for fun.
Does he think it is strange that someone can't be bothered to walk around the corner from his house to pick up a Nando's, and uses Deliveroo instead?
"I understand this," he says bluntly. "I'm also a computer programmer, sometimes when you are concentrating, you don't want distraction.
"You just want your favourite food at your desk. It's like ordering a pizza."
Dinein - Founded in 2012, a direct rival to Deliveroo in London and Brighton with a similar business model. Delivery charge is based on distance.
Meals - Founded in Bristol in 2012 and now also serving London, bills itself as 'posh nosh takeaway'. Another direct rival with the same business model. It charges £4.99 for deliveries under £15, going down to 99p for orders over £50.
City Pantry - Founded in 2014 and based in London. An online catering marketplace focusing on street vendors, delis and other places that wouldn't normally do takeaway. Focused on catering for events like weddings and office lunches.
GrubHub - American company founded in 2004 and listed on the US stock exchange. Operates in US and London, working with around 35,000 takeaway restaurants.
Muncherry - California business set up by busy parents in 2010. Its own chefs prepare fresh meals, to be warmed in the customer's microwave on delivery.
Blue Apron - American company that delivers "perfectly portioned ingredients" for customers to cook at home.
Persuasive challenge
Back at Dishoom a tablet computer sits in the kitchen, synced to Deliveroo's app. This is how the restaurant's chefs know when new takeaway orders come in, and the same system alerts the couriers.
Of course there is still a stigma attached to being a restaurant that does takeaway, serving food in boxes instead of on plates.
Deliveroo itself boasts on its website that it does not sign up "low-quality takeaway restaurants".
Yet Mr Shu admits that it can be a challenge to persuade more expensive restaurants to sign up.
The quid pro quo is that they get more custom - attractive to a restaurant like Dishoom, which is off the beaten track.
And the restaurants have minimal risk, as the overheads of the takeaway business are in effect outsourced to Deliveroo, which charges the eateries a percentage of the order value.
It's an attractive formula made more feasible by mobile, internet technology. Direct competitors like Dinein and Meals have spotted the same gap in the market.
The cost for members of the public using Deliveroo is menu price plus £2.50 (as long as the order is over £15, below and the fee goes up to £4.50).
Is this perhaps more in line with an investment banker's lunch budget?
You can share with colleagues points out Mr Shu, so if five people order food, then it's only 50 pence each.
Of course most dedicated takeaway restaurants offer free delivery.
Baby steps
Rafal's next bike mission is from the Dishoom restaurant. The job info appears through an app on his mobile phone - he is able to read it despite a heavily cracked screen. An occupational hazard, he says with a smile.
Delivering this one involves a longer cycle, with some generous inclines, to Upper Street in the heart of the Islington.
After a short period of confusion, involving map re-checking and a phone call, he establishes the correct door in the Georgian terrace. There is a tense wait, before a woman appears at the door.
Why did she choose this method?
"I've got a six-month-old baby asleep upstairs in his cot, so I couldn't leave the house," she explains. "I might end up just eating cereal or toast, because I'm a busy mum, Deliveroo means I can have a proper meal."
Who eats?
Geography determines the kind of person calling on their services, says Mr Shu. He says that in the Mayfair area of central London, the typical customer is a hedge fund business, while in east London it is a lot of single people, and in Chelsea, west London, it is typically families.
He reckons it's about two-thirds dinners, one-third lunches.
The company does not disclose its number of orders or turnover, but the service has grown quickly since 2012, and now also operates in Brighton, Oxford, Cambridge, Reading, Manchester, Birmingham, Bristol, Nottingham, Edinburgh and Glasgow.
And outside the UK, it branched out into Dublin and Berlin earlier this year.
"We plan on being in 30 cities by the end of the year," says Mr Chu.
With stiff competition, that kind of growth will depend on getting the right price points for the business model.
And of course there is the danger that in the midst of summer, many people will prefer to take a pleasant stroll to go and get their own food.

England's women completed their World Cup preparations by beating Japan at the Four Nations Tournament.

Alex Danson and Lily Owsely scored in each half to earn a 2-0 win.
England's men were defeated 3-2 by Belgium as they continued their poor form ahead of the World Cup, to be played in the Netherlands from 31 May.
Goals from Iain Lewers and Ashley Jackson were not enough to salvage a draw as Belgium held on for victory in their final match in Germany.
England's women had failed to win in their previous two fixtures in Dusseldorf, losing 4-2 to Australia and 3-1 to Germany.
"This was a much better technical performance", said head coach Jason Lee. "There was much more fight and endeavour in the group, and it's a good performance to take forward."
England's men end their participation at the competition with one draw and two defeats, having followed an opening day 3-1 loss to the Netherlands with a 2-2 draw against Germany.
"It was a game of contrast with plenty of good signs but also some disappointment," said head coach Bobby Crutchley. "We didn't utilise good circle possession to create clear goal scoring opportunities and our reactions were slow in front of goal."


A device the size of a paper clip inserted in the groin has shown promising results in lowering blood pressure, scientists say.

In a study of 83 patients, published in The Lancet, those who received the device experienced an immediate reduction in blood pressure.
But one-third also developed swelling in their leg which needed treatment.
Experts say the device could be a new way of controlling blood pressure, particularly in hard-to-treat cases.
High blood pressure affects one in three adults in the UK, with around 5% of this group suffering from resistant hypertension, which does not respond to medication.
High blood pressure is dangerous because it causes strain on the vessels carrying blood around the body.
This can cause vessels to become clogged up or to weaken, which can cause damage to the heart or brain.
High blood pressure also increases the risk of stroke, heart attack, heart failure, kidney damage and eye problems.
The device, called a coupler, made by ROX Medical in California which also funded the study, creates a chamber between the artery and vein in the upper thigh which appears to help lower resistance and bring blood pressure down.
Researchers at Queen Mary University of London, which led the study, tested the device on 42 patients with high blood pressure which had not responded to at least three types of drug treatment.
They compared the effects with 35 patients who were given the standard medical treatment for uncontrolled high blood pressure.
Patients were drawn from 16 centres across Europe.
The study found "significant reductions in blood pressure" in the coupler group six months after the device was implanted.
For patients in this group, there were fewer hypertensive complications and fewer hospital admissions for high blood pressure emergencies.
Patients who had the coupler inserted were also able to reduce their medication.
However, the device did have side-effects. In around 29% of patients, swelling developed in the leg in which the coupler was inserted.
This required another short procedure to insert a stent in the vein.
Lead author Dr Melvin Lobo, from Queen Mary University of London, and director of Barts blood pressure clinic, said this was an easy thing to do and was probably due to turbulence caused by the device in the thigh.
But he acknowledged there was more to learn about the device.
"We need more research to explore the long-term effects of the coupler, better understand its safety and understand more about how it works within the body.
"We must find better means of treating high blood pressure as drugs do not work for everyone and the coupler is a big step forward in our search for alternative treatment."
Prof Tom MacDonald, president of the British Hypertension Society, and professor of clinical pharmacology at the University of Dundee, said the device could be "a fantastic thing for patients".
"It's another potentially great advance in the treatment of hypertension.
"It's not without its problems, but the beauty of it is you can reverse it, and it can be given to people on top of hypertension medication.
"We now need more rigorously controlled studies and a definitive trial before it can be funded for the NHS."
