After he  to chat show host Oprah Winfrey, disgraced cyclist Lance Armstrong detailed more revelations in the second instalment of their two-part interview.

Here, BBC Sport looks at some of the key moments from the second part of the "no holds barred" interview in what is one of the most high-profile stories in sporting history.
Oprah Winfrey: Every article I've seen and everything I've written begins with the word disgraced. Do you feel disgraced?
Lance Armstrong: "Of course but I also feel humbled and I feel ashamed. This is not good stuff."
What was the most humbling moment that brought you face-to-face with yourself?
"I believe it was a Wednesday. [Sponsors] Nike called - this isn't the most humbling moment, I'll get to that - and they said basically that they were out. OK? And then the calls started coming. Trek, Giro, Anheuser-Bush..."
On the same day, the same couple of days?
"Yeah, a couple of days. Everybody out, still not the most humbling moment. Not a fun period."
How did that hit you, though?
"You know, in a way I just assumed we'd get to that point. The story was getting out of control, which was my worst nightmare. I had this place in my mind that they would all leave. The one I didn't think would leave was the [Livestrong] / Foundation.
"That was the most humbling moment. To get that phone call - first to step down as chairman and stay on the board, but that wasn't enough for the people and for our supporters and then a couple of weeks later the next call came to step aside. They said 'we need you to consider stepping down for yourself' and I had to think about it a lot.
"The Foundation is like my sixth child and to make that decision and to step aside was big. It was the best thing for the organisation but it hurt like hell. That was the lowest."
Of everything that has happened in this entire process, in this fall from grace, has that been the toughest?
"That was the lowest, the lowest."
Can Livestrong live without your story?
"I certainly hope so. Yeah, I hope so."
Because your story transcended sports and gave hope to so many people fighting cancer. I have this email that a friend sent to me after finding out I was going to be doing this interview and it said 'I have heard that he is a real jerk but I will always root for Lance. He gave me hope at a very dire time. My first-born son had just been diagnosed with leukaemia two weeks before his first birthday. I'm in intensive care barely able to breathe and my brother sends me Lance's new book, It's Not About the Bike, I read it cover to cover through the night, it showed me that there was hope for my son to not only live but to thrive. I had a choice to make that night on how I would respond to my son's illness and teach him how to face the world. My prayer to Lance is that as he faces his demons he remembers it's not about the bike.
"Amen."
Are you facing your demons?
"Absolutely. Absolutely, yeah. It's a process and I think, you know, we're at the beginning of the process."
What has been the financial cost? Have you lost everything?
"I've lost all future income. You could look at the day and a half when people left. You asked me the cost. I don't like thinking about it but it was a $75m day. All gone and probably never coming back."
How did it hit you?
"I've been to a dark place that was not my doing where I didn't know if I would live a month, six months, a year, five years, 10 years and it has helped me now. This is not a good time but it isn't the worst part of my life. You can't compare this to an advanced diagnosis. That sets the bar. It is close but I'm an optimist and I like to look forward. This has caused me to look back and I don't like that. I'm like my mother like that. We don't talk about the past. I've never spoken about my biological father."
So you came back and you didn't believe it was possible to win seven Tours without doping but you came back not going to dope and you expected to win still?
"Yes, because I thought and still think the sport was very clean. There really was a major shift in the mid-2000s with the biological passports. I thought I was competing on a level playing field.
"I didn't expect to finish third - I expected to win like I always expected and at the end I said I just got beat by two guys who were better. It doesn't sound like what I would say."
Were there people who cared about you who knew about this who wanted you to stop the lying and the doping?
"Yes."
Was there anything they could have said or done?
I can look at what I did, cheating to win bike races, lying about it, bullying people, of course you're not supposed to do those things - that's what we teach our children
"Probably not. If I could say one name - Kristin [ex-wife and mother of his eldest three children]. She is a smart lady. She is extremely spiritual and she believes in honesty, integrity and the truth and believes that the truth will set you free. We believe differently on a lot of things. We have three kids together, they deserve the honest truth and a dad that is viewed to them as telling the truth."
Was there anybody who knew the whole truth?
"Yeah."
Let's go back to Kristin. Did she have conversations with you about stopping or getting out?
"I saw her at the kids' game two days ago and said if this comes up can I talk about this and she said yes. She was not that curious. Perhaps she didn't want to know. She certainly knew but on a need-to-know basis. I guess I protected her a little bit from that. The thing about her and my doping and this comeback was she was the one person I asked if I could do that, if I could come back.
"It was a big decision. I needed her blessing. And she said to me, you can do it, under one condition, that you never cross that line again [the line of drugs], and I said you've got a deal and I never would have betrayed that with her. It was a serious ask, a serious commitment. She gave me her blessing. If she would have said no, I don't like this idea, I would not have done it. But I gave her my word and I'll stick to it."
You and Kristin have three children together, what do you tell Luke, he's 13, you've been fighting this thing all his life. What do you tell him and the girls what's going on?
"They know a lot. They hear it in the hallways. Their schools, their classmates have been very supportive. Where you lose control with your kids is when they go out of that space, Instagram, Facebook, Twitter, in the feedback columns."
But what did you tell him?
"First I want to tell you what happened. When this all really started, I saw my son defending me, and saying that's not true. What you're saying about my dad is not true.
"That's when I knew I had to tell him. And he'd never asked me. He'd never said 'dad, is this true?'. He trusted me. I heard about it in the hallways….."
What did you say to him?
"At that time, nothing, but that's the time I had to say something. I heard he was defending me and it gets ugly and at that point I decided it was out of control and I had to have a talk with him here over the holidays."
What did you say?
"I said there have been a lot of questions about your dad any my career and whether I doped and I've always denied it and been ruthless and defiant which you have seen, which makes it even sicker but I want you to know that it is true. Then there were the girls who are 11 and they didn't say much. They just accepted it and I told Luke 'don't defend me anymore, don't'."
How did he take it?
"He has been remarkably calm and mature about it. I told him 'if anyone says anything to you, do not defend me, just say 'Hey, my dad says he is sorry'. He said 'I love you, you're my dad and this won't change that'. I had expected something.
Did you expect defiance? Anger? Disappointment?
"Thank God he is more like Kristin than he is like me."
What about your mother?
"She is a wreck and she is not the type of person that would call me and say 'Lance, I'm a wreck' but my stepfather called and told me she was having a hard time. I said she is a tough lady and has gotten through every other tough moment. Then we were facetiming with my kids and I saw my mum and she was a wreck. It took seeing her to really realise that this has taken a toll on her life."
A lot of people think you're doing this so you can come back to sport…
"If you're asking me if I want to compete again, the answer is hell yes, I'm a competitor. It's what I've done all my life. I love to train. I love to race, I love to toe the line. And I don't expect it to happen."
Do you want to compete again?
"Not the Tour de France but there are lots of other things I could do but can't do because of this punishment [lifetime ban]. If there is a window, would I like to run the Chicago Marathon when I'm 50? I would love to do that but I can't. I can't compete in any event that is sanctioned by a governing body. I would love the opportunity to compete but that isn't the reason why I'm doing this.
"It might not be the most popular answer but I think I deserve it, maybe not right now. When you see the punishment - I would go back and say you are trading my story for a six-month ban so I got a death penalty meaning I can't compete. I'm not saying that is unfair but it is different."
Are you hoping this conversation, your admission that you wished you had done things differently with Usada, that your lifetime ban will be lifted?
"Er, selfishly, yes. But realistically, I don't think that is going happen and I've got to live with that."
There's been a lot of talk about what you were going to say. What was your intention, your hope that would come out of it?
"The biggest hope and intention was the wellbeing of my children. The older kids need to not be living with this issue in my life. It's not fair what I did to them and also for the little ones, they are two and three. They obviously have no idea but they will learn it. This conversation will live forever. That dumb tweet with yellow jerseys lives for ever. So I've got to get that right for them as they enter the depth of their lives."
Do you think you've got what you deserve? For a long time, you were saying everyone was on the witch hunt for you. Do you think, considering how big you were and what your name and brand stand for, you got what you deserved?
"I deserve to be punished. Not sure I deserve a death penalty."
So was it just you being your cocky, arrogant, jerk self that sent that tweet of you lying there with all the jerseys?
"Yeah, that was another mistake."
The wolves are at your door and you tweet that. What was that?
"That was just more defiance. What's scary is I thought it was a good idea."
You did?
"At the time."
So tell me, when something this gargantuan happens in your life, how has it changed the way you see yourself? Or has it changed the way you see yourself?
"Not completely. This is heavy and this is messy and this is not something I can sit with and then leave and go 'OK, we're all good'."
You mentioned therapy earlier, are you doing therapy?
"Yeah. Over the course of my life, I've done it sporadically. I'm the type of person who needs to not do it sporadically. I've had a messy life, but it's no excuse. This is going to be a long process."
Do you have remorse? Is there real remorse or a sense of sorry you got caught?
"Everybody that gets caught is bummed out they got caught. I'm only starting and I will continue with the ripple effects, people who are sitting there today are still true believers and will hear something different.
"Do I have remorse? Absolutely. Will it grow? Absolutely. This is the first step and these are my actions. I am paying the price but I deserve it."
Do you owe ]Sunday Times journalist] David Walsh an apology?
"That's a good question."
Do you owe David Walsh an apology, who for 13 years has pursued this story, who wrote for the Times, who has now written books about your story and about this entire process?
"I'd apologise to David. I've had a couple of these conversations."
What do you say to the woman who wrote that email [above] and those millions of people who believed?
"I say I understand your anger, your sense of betrayal. You supported me forever, through all of this and you believed and I lied to you and I'm sorry. I will spend - and I'm committed to spending - as long as I have to make amends knowing full well that I won't get very many back."
Are you in a space where you're not apologising but you can begin to feel how you shattered other people's lives?
"Yeah. Yeah. Yeah. And I don't need to be back in that place where I can slip like that and take things for granted and abuse privilege. If I had one of my kids act like that, I'd be apoplectic."
We all know when you're famous, people love to see the rise and they also love to see you stumble and fall. Will you rise again?
"I don't know. I don't know. I don't know what's out there. I do not know the outcome here. I'm getting comfortable with that. That would have driven me crazy in the past. I'm getting there. I need to get even more there. I'm deeply sorry for what I did. I can say that thousands of times. It may never be enough to come back."
Last Wednesday night, Travis Tygart of Usada told 60 Minutes Sports that someone on your team offered a donation which Usada did not accept. He said it was over $150,000. Were you trying to pay off Usada?
"No, that is not true."
That's not true?
"That is not true. In the 1,000-page reasoned decision that they had issued, there was a lot of stuff in there, everything was in there, why wasn't that in there? Pretty big story. Oprah, it's not true."
No-one representing you…
"Nobody, I had no knowledge of that but I asked around. Nobody, not true."
And you are Lance Armstrong and you run your own show so if somebody was going to offer $150,000, you would know about it?
"I think the claim was $250,000, it was broad number but they narrowed it down. That's a lot of money. I would know."
And you're saying that's not true?
"That's not true."
When something like this happens, what you hope is that it causes a change within you. Has it happened to you yet?
"I'd be lying if I said it has. I keep going to the idea and the word 'process' - I have work to do and there is not going to be one tectonic shift."
Are you a better human being today because this happened? Did it help you become a better human being?
"Without a doubt and again this happened twice in my life. When I was diagnosed I was better and smarter after that and then lost my way and this is the second time. It is easy to sit here and say I feel better and smarter but I can't lose my way again.
"Only I can control it and I'm in no position to make promises. I will slip up every now and then. The biggest challenge of the rest of my life is to not slip up again and not lose sight of what I have to do. I had it but things got too big and too crazy. Epic challenge."
It's an epic story. What's the moral to the story?
"I don't have a great answer there. I can look at what I did, cheating to win bike races, lying about it, bullying people, of course you're not supposed to do those things - that's what we teach our children. That's the easy thing. There's another moral to this story. For me, I think it was about that ride and about losing myself and getting caught up in that and doing all those things along the way. And then the ultimate crime is the betrayal of these people who support me and believed in me and they got lied to."
You know what I hope the moral to this story is? It's what Kristin told you: the truth will set you free.
"Yeah. She continues to tell me that."


Liverpool striker Andy Carroll has been included in England's 23-man squad for Euro 2012, but there is no place for Manchester United's Rio Ferdinand.

The 33-year-old is a surprise omission but Chelsea's John Terry has been named in a squad captained by Steven Gerrard.
There are call-ups for uncapped Arsenal midfielder Alex Oxlade-Chamberlain and Norwich goalkeeper John Ruddy.
Liverpool winger Stewart Downing and Manchester United striker Danny Welbeck have also been picked.
"It's not been an easy squad to put together," said boss Roy Hodgson. "But I'm pleased with the squad I've put together and I think it's a well-balanced squad."
Gerrard, who captained Liverpool during Hodgson's time as manager at Anfield, also led England at the 2010 World Cup.
"I know him as a player and a person and how committed he is to the England cause," explained Hodgson.
"He will help me build the team unity and environment we need to thrive in a tournament."
As expected, Wayne Rooney is selected despite being suspended for the first two games of England's Group D campaign, against France on 11 June and Sweden four days later.
"After the debacle in South Africa, everyone was clamouring for youth. I'm slightly surprised Roy Hodgson has only named four forwards considering he will be without Wayne Rooney for a couple of games."
In addition to Carroll, Welbeck and Rooney, Hodgson will take Jermain Defoe - who has not played a competitive match for England since September 2010 - as a striking option.
Birmingham goalkeeper Jack Butland is among the list of five standby players, which also comprises Adam Johnson, Daniel Sturridge, Phil Jagielka and Jordan Henderson.
Barring injury, Johnson will miss out on a major tournament for a second time, having been axed from Fabio Capello's provisional World Cup squad in 2010.
Hodgson's wide players are Ashley Young, Theo Walcott, James Milner, Downing and Oxlade-Chamberlain.
There is no place for Manchester United's Michael Carrick as Gareth Barry, Steven Gerrard, Frank Lampard and Scott Parker - who is struggling with an Achilles injury - take the central midfield berths.
Manchester City right-back Micah Richards also misses out as Hodgson names only seven orthodox defenders, including Phil Jones and Joleon Lescott, who are both capable of filling more than one position.

Tottenham right-back Kyle Walker was ruled out with a toe injury.
Ruddy joins Joe Hart and Robert Green in the goalkeeping contingent.
"It's a real honour for me and hopefully it's an indication as to how far I have developed as a player," said Ruddy.
"Playing for my country has been a dream of mine, of course it has.
"I'm under no illusions as to the quality of Joe Hart and Rob Green and that I will be number three keeper. But I'm really looking forward to training with them and getting down to some hard work."
The Football Association's planned training camp in Spain has been cancelled.
Instead, England will meet up in Manchester on Wednesday before flying to Norway on Friday for their friendly in Oslo on 26 May.
Seven days later, they face Belgium at Wembley - although Ruddy will be missing having been given special dispensation to leave the squad for his wedding on 2 June.
Goalkeepers - Joe Hart, Robert Green, John Ruddy.
Defenders - Leighton Baines, Gary Cahill, Ashley Cole, Glen Johnson, Phil Jones, Joleon Lescott, John Terry.
Midfielders - Gareth Barry, Stewart Downing, Steven Gerrard, Frank Lampard, James Milner, Alex Oxlade-Chamberlain, Scott Parker, Theo Walcott, Ashley Young.
Strikers - Andy Carroll, Jermain Defoe, Wayne Rooney, Danny Welbeck.
Standby - Jack Butland, Phil Jagielka, Jordan Henderson, Adam Johnson, Daniel Sturridge.


The Belfast Giants returned to winning ways on Wednesday as they defeated Dundee Stars 5-2 at the SSE Arena.

The Giants had lost 4-1 to Braehead Clan at home on Tuesday night but this victory sees them remain six points adrift of leaders Cardiff Devils.
Mike Radja (2), James Desmarais, Michael Forney and player-coach Derrick Walser found the net for Belfast, who have three games in hand over Cardiff.
Lou Dickenson and Mikael Lidhammar were the scorers for Dundee.
Goals from Dickenson and Radja saw the sides tied at 1-1 after the first period, with Desmarais and Forney on target to move the hosts two ahead by the end of the second period.
Walser scored for Belfast, Lidhammar pulled one back, but Radja completed the scoring soon after to make it a convincing triumph for the Giants.
The Giants had been on a four-game winning run, before they went down to Clan on Tuesday.
That reverse was their sixth in 12 games in Belfast, but the success against the Stars will boost confidence in the Belfast camp.
Cardiff saw off Manchester Storm 3-2 on Wednesday to maintain their advantage at the top of the standings.
The Giants will host Coventry in their next fixture in Belfast on Saturday night.


Rochdale and Scunthorpe cancelled each other out by trading second-half goals in a League One draw.

The home side enjoyed the greater share of possession in the opening period, but home goalkeeper Josh Lillis was busier than Scunthorpe counterpart Matt Gilks, who did not have a save to make in the opening 45 minutes.
The Rochdale goal came under threat when a misjudged back pass by Jamie Allen from the halfway line looked short of legs, presenting an opportunity for Paddy Madden. Fortunately for Keith Hill's side, Lillis read the danger early and raced out of his area, winning the crucial challenge for the ball.
Lillis also saved well when Reece Brown's poor header let Josh Morris in down the left flank.
After the break, Dale improved with the introduction of striker Steven Davies and his diving header gave the home side the lead, the frontman meeting Ian Henderson's flick towards the back post.
It was a short-lived lead, however, as fellow sub Duane Holmes slipped a neat finish beneath Lillis.

Investors dumped shares of Abercrombie & Fitch on Monday after the Ohio clothes retailer said it had broken off talks with potential buyers.

The firm, which once drew teen shoppers with ads featuring scantily-clad models, has struggled more recently with falling sales.
But shares rose in May after the firm, which also owns the Hollister brand, said it was considering selling itself.
The stock plunged more than 21% on Monday after those talks ended.
Abercrombie boss Arthur Martinez said the firm's business plan offered a better bet for shareholders than a sale.
"We believe in the prospects for our business and the opportunities for our brands," he said in a statement.
"We are committed to taking sound, aggressive action to deliver enhanced performance and long-term stockholder value."
Abercrombie reported a quarterly loss in May, with sales down 4% year-on-year. The firm is one of many US retailers seeing uncertain growth this year.
But Mr Martinez said the firm had seen "solid" sales momentum at its Hollister stores and expected to see improvement in the second half of the year.
Abercrombie operates about 900 stores globally. The potential buyers had reportedly included American Eagle and Cerberus Capital Management, a private equity firm.


The pound has hit a fresh 31-year low against the dollar as worries over the UK's exit from the European Union continued to rattle financial markets.

At one point it dropped to $1.2798, before recovering slightly to $1.2932.
Analysts blamed warnings from the Bank of England on Tuesday that Brexit risks were "crystallising" and fears about the UK commercial property market.
The pound has now fallen by about 14% against the dollar since hitting $1.50 ahead of the referendum result.
"Pessimistic predictions for sterling are coming true," said Andrew Edwards, chief executive of ETX Capital. "The pound is the chief proxy for the post-Brexit mood in the markets."
Against the euro, the pound was down 0.5% at â‚¬1.1697 on Wednesday, its lowest level since 2013.
On the UK stock market, the FTSE 100 index dropped slightly to 6,529.11.
Domestic companies such as supermarkets, housebuilders and banks have fallen sharply, and the FTSE 250 - which contains more UK-focused companies - was down 1% at 15,569.34 in early trade.
Tesco and Morrisons were two of the biggest losers, with their shares dropping 4.9% and 3.4% respectively after analysts warned of a potential price war among supermarkets.
Property-related stocks have been especially hard hit this week after three fund managers decided to stop investors withdrawing money from their UK property funds. Shares in Barratt Developments and Taylor Wimpey fell by a further 4%,
"The suspension of commercial property fund redemptions by a number of big players has precipitated a broader sell-off in the UK property sector including housebuilders and other asset managers," said Michael Hewson of CMC Markets.
European stock markets fell more sharply, with the Paris Cac, Frankfurt Dax and Madrid Ibex indexes all dropping by 1%.
Investors are showing some "buyers' remorse" after last week's stock market rebound and are focusing on "weak spots of the European economy", Mr Hewson said.
Europe's financial sector, in particular, is under pressure after the European Central Bank warned that Italian lender Banca Monte dei Paschi di Siena, the world's oldest bank, had dangerously high levels of bad debt.
Earlier, Asian stock markets had closed lower, with Japan's Nikkei index down 1.9%.
Government bond yields have also fallen to record lows as investors rush to put money in perceived havens.
Yields on 10-year US and Swiss government bonds hit new record lows, while those of Denmark and the Netherlands dropped to just above zero.
High demand pushes up bond prices, and when the price of bonds rises, their yield falls.
The yield on the 20-year Japanese government bond turned negative for the first time on Wednesday, underlining the hit investors are willing to take to keep their money in rock-solid government debt.
The price of gold also touched a two-year high of $1,371.40 an ounce, as it surpassed the $1,358.20 mark it reached on 24 June in the immediate aftermath of the Brexit vote.


Scottish politicians have been outlining their views on the EU as the Prime Minister said he was "hopeful" of reaching a deal by February.

David Cameron said the in-out vote "would follow" if agreement with EU leaders was reached on his reforms.
The SNP's Stephen Gethins said Mr Cameron does not appear to have confidence in a renegotiation package.
Labour's Ian Murray said he was not aware of any Labour MSPs currently planning to campaign for an EU exit.
Meanwhile, Alex Johnstone of the Conservatives said Europe needs a "different sense of direction".
During an interview on the Andrew Marr programme, Mr Cameron also said he would stay on as PM even if he ended up on the losing side.
Stephen Gethins MP, the SNP's European affairs spokesperson, said: "The deep-seated divisions within the Tory party over Europe are becoming increasingly acrimonious and obvious ahead of David Cameron's EU referendum.
"The very fact that the Prime Minister is even entertaining the idea of a Brexit does not exactly show he is confident of securing a renegotiation package which will satisfy the Tory Eurosceptics .
"The SNP will make the positive case for Scotland and the UK's continued membership of the EU - but Scotland must not be dragged out of the EU against its will."
On Sunday Politics Scotland, Ian Murray - the Shadow Scottish Secretary and Labour's only MP in Scotland - said the "vast majority" of Labour members and supporters are pro-Europe.
He added: "We see the benefits of being part of the European Union. We are a broad church of a party. Both Scottish Labour and the UK Labour party will be campaigning and putting lots of resources behind staying within the European Union because we know it is in Scotland's interests to do so."
Mr Murray said that while it was apparent some Labour MPs would be campaigning in the referendum to leave Europe, he was currently unaware of any MSPs who intended to do so.
While the Scottish Labour Party will campaign to remain in Europe, individual MSPs will be given a free vote on the issue.
Mr Murray added Scottish Labour would share a platform with all parties campaigning to stay in the EU, but Labour would run its own distinct campaign.
Meanwhile, Mr Johnstone - a Conservative MSP who represents north east Scotland - told the programme he supports Mr Cameron's efforts to renegotiate Britain's membership of EU and he will vote in the referendum depending on how successful the Prime Minister is.
He said: "I think we have some serious problems in Europe at the moment. At this time, our direction in Europe is inappropriate."
Mr Johnstone believes the EU has not managed to deal with political problems generated by the refugee crisis, and the economic crisis in Greece and other smaller states.
He added: "Britain needs not to be dragged into that kind of situation against our will. I want a Europe that has a different sense of direction - one that is about opening up trade, opening up competition, opening up opportunity, not providing a political and economic straightjacket that will benefit some countries and disadvantage many more."
Ian Duncan is a Conservative MEP for Scotland. He said there has already been "substantial progress" in reforming the EU.
He told the programme: "There has been an 80% reduction in the laws passing through that particular chamber. That is because of Britain's pressure to do less, and to do less better."
Willie Rennie, the leader of the Scottish Liberal Democrats, said his party is united behind staying in the EU.
He added: "Despite his claims of commitment to it, David Cameron's sloping shoulders threaten the future of this country. By allowing UK government ministers to campaign against him instead of uniting behind him, the Prime Minister is only encouraging party infighting which will detract from the more important issues.
"The leader of the Scottish Conservatives needs to step up to the plate and show leadership in the way her Prime Minister is not.

A US Navy officer has been charged with espionage, accused of passing military secrets to China and Taiwan, according to US military officials.

The Associated Press news agency named him as Lt Cdr Edward Lin, a US citizen who was born in Taiwan.
He is being held in Navy brig in Virginia awaiting a court-martial.
Officials believe he passed information to a Chinese girlfriend, the New York Times reported. Lt Cdr Lin is also charged with lying about his travels.
United States Naval Institute (USNI) News first reported the charges against Lt Cdr Lin. The website said that Lin worked as a signals intelligence specialist on the Navy's EP-3E Aries II reconnaissance planes.
He joined the Navy as an enlisted sailor in 1999 and became a US citizen in 2008.
"I always dreamt about coming to America, the 'promised land," Lt Cdr Lin said when he became citizen. "I grew up believing that all the roads in America lead to Disneyland."


As tens of thousands of civilians continue to flee Islamic State (IS) militants in the Iraqi city of Ramadi, BBC News talks to some of the people who escaped the fighting and still have family members caught up in the conflict.

Mohamed, 19, says he was taken by complete surprise by the sweeping takeover of the city by IS militants last week.
When he went to bed on Friday evening, everything seemed to be normal in the city. But by the time he woke up the next morning, he said, "the army had left its positions and IS were there in their place".
Mohamed is a local tribesman, but fortunately for him not a well-known figure because, he says, many "tribal leaders who couldn't escape were killed" soon after IS entered the city.
Other residents have told media outlets that the IS militants were breaking into the homes of policemen and pro-government tribesmen.
It was only after the tribesmen were killed, Mohamed continues, that IS militants announced from a mosque in central Ramadi that they had captured the whole city.
"Now all of the tribes are dead, they've been killed, demolished. The only thing left are the Shia militias and I don't think they're going to do anything to help Ramadi."
Mohamed managed to evade the militants by hiding his weapons and clothes and travelling with the large numbers of families who fled.
He has cousins who remain in the city. He last heard from them on Sunday evening when they called to say they had been surrounded from all sides.
"They called just to say that they were going to die," he says. He hasn't heard from them since.
Like Mohamed, Ahmed also left some family members behind when he fled Ramadi with his wife and two children last weekend.
He says he has been in regular contact with his uncle, who was unable to leave the city because he simply had nowhere else to go.
"Whoever was against IS was killed by the militants and my uncle says there were bodies in the streets. IS has also raised flags on some of the buildings in the city," Ahmed says.
The militants allowed some people to flee the city, he explains, with families waving white flags to show they had surrendered.
The loss of Ramadi represented more the failure of the Iraqi armed forces than the success of IS, he argues, saying that the army showed a lack of faith and weakness.
"They just don't have the commitment to fight and they gave up."
Ahmed described life under the militant group as an "unknown", saying he could not "live in an atmosphere filled with death, fear, horror and slaughtering".
"I would never feel safe living with people that are against life and humanity. They kill for the simplest reasons."
Ahmed has joined thousands of refugees in Khaldiyah, to the east of Ramadi.
Mohamed ended up in the same place, where he found 15 people packed into each room.
And when the battle started to turn eastwards, Mohamed decided to move on to Baghdad, where some of his uncles, who were injured in the IS attack, could receive medical treatment.
He says the IS militant advance was akin to ants that "come out from the ground".
"I think they just dig into the ground and come out from another area. We were surprised when we saw them all in Ramadi."
Ammar is an Iraqi refugee currently in Turkey. His main concern rests with his family, who are currently stuck in the Habbaniyah area.
He told the BBC he was fearful for their safety, and has been urging them to consider where they could flee to.
Some 3,000 Shia militiamen have been deployed in a military camp in the area ahead of an attempt to recapture the city.
Despite this, life is normal in Habbaniyah right now, says Ammar, who is in regular contact with his sisters and father. "They don't have electricity, but that's just normal by Iraqi standards," he jokes.
However, his family are planning to leave because the fighting is getting too close for comfort. "They are worried to death and they don't know what to do - they don't have many choices left."
Ammar had first-hand experience of dealing with an IS onslaught when his house was on the frontline of the IS advance into Fallujah at the end of 2013.
"I left the first hour of the first day Islamic State militants entered the city," he recalls. He has since heard from his former Baghdad neighbours that his home was largely destroyed in bombing by Iraqi government forces trying to recapture the city.
He moved from Fallujah first to Habbaniyah, then onto Baghdad and finally Turkey. In all that time, he says he has not once seen an IS fighter. "It feels like we're still running from them."
He says the battle against IS is "not taken seriously - it's like a game of cat and mouse".
But, he continues, "I hope and think every game has an end - I just don't know when this will be."

A woman allegedly raped by footballer Ched Evans in a hotel had "no idea what on earth was happening", a court heard.

The Chesterfield striker denies raping the 19-year-old at a Premier Inn in Rhuddlan, Denbighshire, in May 2011.
Mr Evans, 27, was found guilty of rape at Caernarfon Crown Court in 2012, but his conviction was quashed in April.
The prosecution told his retrial at Cardiff Crown Court the woman had been intoxicated and could not have consented to sex, as Mr Evans claims.
Simon Medland QC, prosecuting, said the woman "did not even know Ched Evans was having sex with her" in the hotel on 30 May 2011.
The woman was "very drunk" and believes her drink may have been spiked, Mr Medland said, although not by Mr Evans.
"She was that intoxicated - for whatever reason - that she didn't really know what on earth was happening," he added.
"The facts of this case show that she was raped by this young footballer in that room, not that she had consensual sex with him."
The alleged victim met Mr Evans's friend and fellow footballer Clayton McDonald at Rhyl's Zu bar in the early hours of 30 May.
She got a taxi to the Premier Inn with Mr McDonald, where Mr Evans had booked a room.
Mr McDonald, who previously played at Manchester City and Port Vale, telephoned Mr Evans and said: "I've got a girl", Mr Medland told the jury.
About 15 minutes later, Mr Evans arrived at the hotel and got a key to the room. He is then alleged to have raped the woman before "surreptitiously" leaving via the fire exit.
Mr McDonald, who now plays at Redditch United, was acquitted of rape at the original trial in 2012.
During Tuesday's hearing, the jury - consisting of five men and seven women - was told by the judge, Mrs Justice Nicola Davies, to disregard any previous publicity of the case.
"There has been publicity in respect of these legal proceedings. If you have heard or read about it, that is the proceedings, in the newspaper, television, radio or social media, you must ignore it," she said.
The case was opened and adjourned for the day and will continue on Wednesday.


Bournemouth have signed Chelsea full-back Nathan Ake on a season-long loan.

Ake, 21, spent last season on loan at Watford, playing 28 times as the club finished 13th in the Premier League and reached the FA Cup semi-final.
The Netherlands Under-21 defender was the Hornets' young player of the year.
Ake signed a new five-year contract at Chelsea last summer and has made 12 first-team appearances for the Blues, as well as playing five times for Reading during a 2015 loan spell.


The Scottish government is proposing a radical extension of the ways electronic tags can be used on offenders, BBC Scotland has learned.

Sobriety tags, GPS tracking and tagging as an alternative to remand would be used in Scotland for the first time.
Sobriety tags, which respond to the ethanol levels in a person's sweat, are among the pilots to be announced.
They would be used as an alternative to prison for those who offend under the influence of alcohol.
The changes will require new regulations and legislation.
Under the proposals, other pilots will be announced in the next couple of months.
All the proposals have been recommended by the expert working group on electronic monitoring, which was created by the Scottish government two years ago.
Tagging has been available in Scotland for almost 15 years and used predominantly to confine offenders to their homes overnight as an alternative to prison or under early release from jail - referred to as Home Detention Curfew.
There are currently more than 1,000 offenders tagged in Scotland.
But under the proposals, in future, tagging will be used as an alternative to remand in prison and as a condition of bail.
And GPS tracking will be used for the first time to monitor certain offenders' movements.
Another option is "voluntary" electronic monitoring for offenders willing to work with agencies to try to stop shoplifting, housebreaking and gang involvement.
The report also calls for monitoring alongside social work support.
Robert Johnson has been tagged more than once.
On one occasion he was sent to Barlinnie prison for drugs offences and released early on Home Detention Curfew.
Now 35, he says he has grown up and that he has not offended for more than two years.
He says that being tagged gave him the time and opportunity to re-connect with friends. He has now started up a cafÃ© with some of them.
"When I was in prison I was ashamed and embarrassed and I didn't want my children to see me there in a place like that.
"Every dad wants to be superman to their children and I didn't want them to see me there, to see me exposed.
"Being at home with a tag and being able to spend time with my family and start looking at education and work, and being with my children, money can't buy something like that."
He added: "In prison you're left in your cell for 23 hours a day locked up with not a lot to do and the chances are if you do do something it's not going to be something worthwhile. On Home Detention Curfew you can be home with your family and your children and start rebuilding your life."
Justice Secretary Michael Matheson said he wanted Scotland to look to the system used in the Netherlands which focuses on outcomes and support.
He hopes the extension of tagging will form part of extensive changes to the whole penal system.
"Rather than just deciding on what kind of electronic monitoring they're going to use, they work out what they're trying to achieve first of all and then look at whether electronic monitoring would help to achieve that aim," he said.
"And it could be different types. It could be GPS or the radio system which we have at the present time. We want to focus on outcomes.
"The report highlights that we could use electronic monitoring in a much more effective way, for example, for individuals remanded into custody."
Angela Smith, service director at G4S Monitoring Technologies & Services in Scotland, said the new system would mean that the numbers of offenders tagged across the country in the future could be "unlimited".
"This is not a soft option. It is a restriction placed not only on offenders but also on their families," she said. "But it does allow them to stay with their families and maintain their jobs and keep relationships together."
In England and Wales electronic monitoring has faced some controversy with a number of high-profile cases in which tagged offenders have been caught committing further crimes. In 2010 a man wearing an electronic tag in Manchester was left dead in his flat for weeks before his body was found.
Stirling University criminologist Hannah Graham said: "England and Wales have had some issues and scandals with their uses of electronic monitoring, whereas Scotland's approach has stayed fairly simple, stable and small in scale.
"The expert group's recommendations imply Scotland will take a more European approach, learning from the Dutch and Scandinavians as leading examples of how to use electronic monitoring well.
"There's evidence to suggest this is a better and bolder direction for us to pursue.
"But it's difficult to predict how much the use of tagging will increase because this depends on whether these recommended changes are embraced by decision-makers such as sheriffs, some of whom barely use it currently."
She added: "There's an acute need to reduce Scotland's disproportionately high prison population - making better use of electronic monitoring within community sentences offers one way of trying to do this."
Mike Nellis, Emeritus professor of law at Strathclyde University, previously worked as a social worker with young offenders.
He told the BBC's Good Morning Scotland radio programme that tagging should be used in conjunction with other services.
"The technology by itself is very limited if you're trying to change any type of behaviour. Certainly, if we're talking about people with alcohol problems, they have to have the services to help them deal with their alcohol problems."
He added: "Some people are given a sense of self-discipline by having to wear the alcohol monitoring device or indeed any other form of electronic monitoring devices, and I think part of the art of using electronic devices wisely and well is to help people to understand that this is something that they can use to assist them on their journey of desistance."
Scottish Conservative justice secretary spokesman Douglas Ross said there was a place for electronic tagging but he could not accept the "creeping expansion" replacing custodial sentences for serious criminals.
He said: "We saw in recent weeks how some rapists have been escaping jail and instead handed community sentences.
"That's an indication that, when the Scottish government insists on an alternative form of punishment, it inevitably gets used on the wrong people.
"In order to retain public confidence in tagging, this expansion will have to be monitored exceptionally closely."
Scottish Labour's justice spokeswoman Claire Baker said Scotland has one of the highest prison populations in Europe and called for credible and robust alternatives.
"However, for tagging to work both the courts and the general public must have confidence in it as an alternative," she added.
"Without that we will still see people sent to prison on remand or for short sentences.
"Therefore the Scottish Government must ensure that electronic tagging is fully resourced and monitored, yet with cuts to the budgets of the police, our courts, and local authorities, this will be challenging."


Peterborough United have signed Newport left-back Andrew Hughes and Mansfield centre-back Ryan Tafazolli.

Hughes, 24, has agreed a two-year deal after rejecting an offer from the Welsh side, for whom he played 151 games.
Tafazolli, also 24, was also offered a new contract at his previous club, for whom he appeared 118 times, and signed a three-year deal at League One Posh.
Meanwhile, former Derby coach Lee Glover has been named as Grant McCann's assistant manager.
Ben Mackenzie has been appointed as head of sport science at the ABAX Stadium.
Hughes and Tafazolli are Peterborough's second and third signings under McCann, with the latter joining despite reported interest from Sheffield United.
Tafazolli told BBC Radio Cambridgeshire: "There was a lot of interest, but coming from a League Two side I knew the most important thing for me this season was to go to a club where the manager wants me, I've got a good chance of playing and the club will be pushing for promotion.
"It ticked all the boxes for me and it was a no-brainer. Someone used the analogy of football being like a game of snakes and ladders. You can get on a big ladder (and go up) and get on a snake and come back down again.
"It's all about stepping stones and I think this is the perfect one for me."

Regional inequality in the UK is becoming more pronounced, Bank of England chief economist Andrew Haldane has warned.

London and the South East are the only places in the UK where income per head is back above pre-financial crisis levels, he said.
Net wealth has also fallen in places such as the North East of England.
But without action by the Bank, the regions could have faced economic contraction, he added.
"The UK, I think, is towards the bottom of the league table within Europe in terms of its degree of difference across regions," Mr Haldane told the BBC economics editor Kamal Ahmed.
Britain's inequality map - stark and growing
He said that wage differences between regions of the UK could differ by as much as 50% and that the productivity gap between regions could be as much as 60%.
Mr Haldane also said there had not been much evidence of those gaps shrinking over the past few years.
"If anything these gaps, which are of long standing have nudged a little wider over the course of the UK's recovery," he said.
There was no single reason why there were such big and persistent differences between regions, he said.
But he thinks differing levels of skills and research and development could be partly to blame.
"Very much more of the research and development occurs, as you might expect, in those high productivity, high income regions of the country," he added.
Mr Haldane said regional inequality was among the most important issues facing the UK.
Reducing the gap could open up considerable opportunities, he said.
For example, he said that if the productivity levels of all companies could be brought up to the levels of those in the most productive parts of the UK it would boost productivity "by fully 20%".
"It would take the UK right up there to rival the Germanies of this world when it came to efficiency and performance," he added.
"That in turn I think would lift wages, it would lift incomes and would lead to a bigger pie as well as more equally redistributed one."
However, the Bank of England lacks the tools to tackle the problem, according to Mr Haldane.
"The tools we have at our disposal are, truth be told... few in number and rather blunt in impact. They tend to work by lifting all boats across the whole of the UK," he said.
Mr Haldane was giving a speech at an iron and steel research centre in Redcar, North Yorkshire.


A detective who allegedly placed a toy monkey on a black colleague's desk has been accused of gross misconduct.

Det Sgt Andrew Mottau is alleged to have told the woman to make him cups of tea "when the black monkey starts to sing", Thames Valley Police said.
He is also accused of making racist remarks and asking her to "embrace" the monkey in the period between 15 August and 15 September 2016.
A four-day misconduct hearing will start in Oxford on 24 April.
The force, which covers Oxfordshire, Berkshire and Buckinghamshire, said it could not say where Det Sgt Mottau is based.


Seven newborn puppies have been found abandoned in a crate in Swansea, three days before Christmas.

The RSPCA was contacted by a dog walker who found the puppies in Penlan on 22 December at about 08:30 GMT.
The dogs, three females and four males and thought to be a rottweiler cross breed, were only a few days old and their eyes had not yet opened.
RSPCA inspector Gemma Cooper said they were "soaking wet and hungry" and would have died had they not been found.
"These poor pups are too young to be without mum and demand around the clock care," she said.
"We are thinking about naming them Holly, Ivy, Angel for the girls and then Noel, Sprout, Pudding and Blitzen for the boys."


For seven years, and in the midst of a gruesome civil war, Soumaia Fergani was the only woman in Algerian football stadiums when she was the country's only qualified female match official.

She now serves as a deputy in the National People's Assembly, but prior to her political aspirations, football was her true passion.
Fergani grew up playing with her brothers in Medea, one hundred kilometres from Algiers. As a student at the University of Blida she pursued a refereeing diploma alongside a bachelor's degree in English Literature.
"When I moved from my town to Blida, I met other female students who played often," she told BBC Sport. "We made our own team of six or seven girls and played indoors after classes. They were really good!"
An opportunity to really test themselves soon arose when the Federation of Algerian Football invited teams from Algeria's 48 provinces to attend a tournament in Annaba.
"We were the worst team there," she recalls. "Nevertheless, we were really proud to participate in such an event."
Some of the women in Annaba saw that the Federation of French Football were organizing a tournament in honour of Human Rights Day, on 10 December 1997.
They resolved to take a punt and write a letter to the FFF on behalf of the Federation of Algerian Football, asking them to invite an non-existent Algerian women's national team.
Twenty days later, the President of the Algerian Federation received a letter informing him the FFF would be delighted to welcome the Algerian Women's National Team for a futsal tournament.
"I barely made the team myself. I was listed as the team's third goalkeeper," Fergani explained.
Algeria's first women's national team were beaten comprehensively in their first non-official matches, but their trailblazing legacy is what will be remembered.
After her exploits with the national team, Fergani worked towards an officiating career and she quickly became Algeria's only qualified female match official.
Political turbulence had plunged Algeria into what is now remembered as 'The Black Decade'.
An Islamist political party swept the preliminary rounds of Algeria's first true democratic elections. In a shrewd move, the military nullified the results of the election, and cracked down on public political discourse.
Football terraces quickly became a place where disenfranchised young men could congregate and voice their frustrations. Never in her wildest dreams did Fergani expect to officiate in such conditions, but a stroke of serendipity forced her out of her comfort zone and into the limelight.
"For seven years, I was the only woman in the stadiums," Fergani recalled. "I started refereeing youth matches before senior matches. Sometimes people came early to watch and when they saw me, said 'Go home and cook couscous. What are you doing here?'"
Although Fergani faced criticism, she also encountered many who supported and helped her.
"One day, after officiating a youth match, I entered the dressing room to change. An old man walked in and said, 'My daughter, I want to ask you for a favour. The match official is not here, I don't think he's coming. This is really a big match, do you think you could replace him?'"
Fergani accepted, not knowing she was to officiate a tense cup tie between NA Hussein Dey and ASO Chlef.
"Fans started whistling when the match started and I was truly petrified. I kept thinking of our first lesson in training: look composed at all times. Even if you are afraid, don't show it," she said.
Fergani's nerves soon settled as she proved her competence and established herself.
"The first call came early in the match. Sure enough, it was the hardest law in officiating: offside. I whistled and raised my hand and surprisingly the entire stadium started applauding. I breathed a huge sigh of relief. Algerians can be tough until you prove yourself."


A British soldier who was killed in Afghanistan on Friday has been named by the Ministry of Defence.

Father-of-four Lance Corporal Matthew Smith, 26, of the Royal Engineers, was shot while on duty in the Nad-e Ali district of Helmand province.
He died of injuries sustained while he was involved in a construction task.
It comes only hours after the MoD named Lt Andrew Robert Chesterman of 3rd Battalion, The Rifles, as the soldier killed on Thursday.
L/Cpl Smith's mother Caroline described him as a "hero" and said he was devoted to his family and four children - Lainie, Ella, Tilli and Jai - aged between one and seven years, and "talked about them endlessly".
Mrs Smith said: "A loving father to four beautiful children, who will be dearly missed by his fiancÃ©e, mother, father, family and friends. Our Hero RIP."
Born in Hong Kong, L/Cpl Smith grew up in Aldershot.
Nicknamed Smudge, he became a soldier in January 2003 and joined the Corps of Royal Engineers in September of the same year.
Since his deployment to Afghanistan with the 30 Armoured Engineer Squadron, 26 Engineer Regiment on 16 March this year, he supported 1st Battalion The Royal Anglian Regiment as a section second in command, crane operator and driver.
He was involved in the construction of a new bridge allowing the local population of Nad-e Ali to cross the Nahr-e-Bughra canal.
His comrades described him as a "big character" who adored his family and would always count down to when he would see them again.
Corporal Matt Copping, 6 Troop Section Commander, said: "He was always proud of his children and showed me new pictures as soon as he got them. Smudge also leaves behind his fiancee Laura, who he adored."
He added: "Lance Corporal Smith's family have lost a major part of their life and my thoughts are constantly with them. I was proud to have known and worked with Smudge; it was a privilege. Not only have I lost a great colleague, but a great mate."
Commanding officer Major Chris Ankers said: "I am proud to have commanded such an honest and professional soldier and to have met such a decent man. He took great pride in his work and inspired those around him, a true leader of men."
Lt Chesterman, a Platoon Commander in C Company, 3rd Battalion The Rifles, was deployed to Afghanistan on 7 April this year.
The 26-year-old, from Bristol, was commanding a vehicle patrol when the lead vehicle was struck by a roadside bomb on Thursday.
The MoD said that as Lt Chesterman moved forward to take control of the situation, insurgents opened fire and he was shot. He was taken to hospital in Camp Bastion but could not be saved.
His father Paul Chesterman said: "We have lost a fine young man. It was readily apparent that Andrew gave himself fully and wholeheartedly to his career in 3 Rifles."


Libya's rival politicians have signed a UN-brokered deal to form a unity government in a nation split by more than four years of conflict.

UN envoy Martin Kobler described the deal as historic, saying Libya had "turned a page" in efforts to achieve reconciliation and stability.
However, the heads of the rival parliaments failed to sign the deal because of major disagreements.
Armed groups which control much of Libya were not part of the talks.
Libya has been in chaos since the 2011 overthrow of long-serving ruler Muammar Gaddafi by Nato-backed forces.
It has two rival governments, one based in the main city, Tripoli, and the other about 1,000km (620 miles) away in the port city of Tobruk.
The signing draws a line under a 14-month political process that gained more prominence in recent months because of the large influx of refugees and migrants to Europe, and the growing threat of Islamic State militancy in the country.
Diplomats put extra pressure on the Libyan delegates in recent weeks because in order to address those issues they need a single government to work with.
Some observers sounded alarm bells ahead of the signing, cautioning that it could further divide Libya if it did not include all the key players - and not everyone was present at the ceremony in Morocco.
A security plan to protect the new unity government - which at the moment only exists on paper - is crucial, and this does not exist.
This latest step is a huge gamble.
It could yet prove to be a springboard for a wider agreement that eventually unites Libya.
But if it fails, it may lead the country into a darker spiral of violence over legitimacy and control.
Amid the turmoil, the country has become a major departure point for some of the thousands of migrants travelling to Europe from Africa.
There is also international concern that the militant so-called Islamic State (IS) group is taking advantage of the instability to expand inside Libya.
Mr Kobler said the new government would have to tackle the dire humanitarian situation in Libya, and fight IS and other jihadi groups.
"You must not forget that this is the beginning of a difficult journey. There is a critical need for national reconciliation [in Libya]," he told the rival politicians.
Around 80 of the 188 members of the Tobruk-based parliament and 50 of the 136 rival lawmakers in Tripoli signed the deal, the AFP news agency quotes participants as saying.
On Tuesday, the heads of the two parliaments, Agila Salah of Tobruk and Nouri Abusahmen of Tripoli, said they had not authorized anyone to sign the agreement on their behalf.
Mr Salah pleaded for more time, warning that "acting hastily would lead to more problems in the future".
Mr Abusahmen said "we will not accept foreign intervention against the will of the Libyan people" referring to the UN-backed deal.
The two leaders met for the first time in Malta on Tuesday.
Mr Salah's parliament is internationally recognised, and based itself in Tobruk after being driven out of Tripoli.


A police and crime commissioner (PCC) who ordered his chief constable to "retire or be removed" said he did not get a fair hearing when he appeared before a committee of MPs.

Gwent PCC Ian Johnston has been accused of bullying Carmel Napier.
He claimed he was made to look like a villain by the Home Affairs Select Committee, which questioned both of them over what had happened.
The committee said he had a "disdainful attitude" to parliamentary scrutiny.
But Mr Johnston told BBC Wales he believed the MPs had already decided what they were going to write before he appeared in front of them in July.
He said: "I don't think they listened at all to the evidence, I think the way the questioning went they had made their mind up about lots of things.
"If you look at the way that it was done, I was the villain of the piece before I even went in there and Carmel Napier was this poor unfortunate woman who had been bullied by this new police and crime commissioner.
"That was the way they presented it."
In June Mrs Napier announced her retirement with immediate effect after a 30-year career in policing, only for it to emerge that she had been forced out after a series of rows with Mr Johnston.
It was revealed that Mr Johnston ordered Mrs Napier to "retire or be removed" as he believed her managerial style was "unacceptably dismissive, abrupt and unhelpful".
The case highlighted the wide-ranging powers enjoyed by PCCs to dismiss chief constables and prompted an inquiry by the committee.
In her evidence to MPs, Mrs Napier accused Mr Johnston of "menacing and bullying" her out of her job.
She said he came to her office and read out a document issuing an ultimatum - leave or face being forced out.
In a subsequent report, the Gwent PCC was criticised by the committee for what they called "this disdainful attitude towards scrutiny by Parliament, as well as an indication of a clear over-sensitivity to criticism".
They pointed out that Mr Johnston had been elected by less than 8% of voters in Gwent and "had managed to side-step the statutory arrangements for local scrutiny of his decision to sack the chief constable".
However, Mr Johnston said he believes the commissioners are "not accountable to members of Parliament".
He added: "A message back for Keith Vaz [chair of the committee], I did not side-step any procedures, I followed the procedures to the letter of the law."


Justice minister David Ford has expressed surprise that First Minister Peter Robinson said his recommendation to change the abortion law on fatal foetal abnormality cases was doomed.

Mr Robinson said proposed draft guidelines offered a better way forward than legislation.
Mr Ford said last month he would ask the executive to approve legislation for abortion in such cases.
He said Mr Robinson had made "a complete U-turn".
The issue of fatal foetal abnormality has been examined by health and justice officials over the past 18 months, following a high-profile case featured on the BBC's Nolan Show.
Mr Ford had put forward his plan for legislation in such cases following consultation on reforming Northern Ireland's abortion law.
However, on Thursday night Mr Robinson told the BBC that draft guidelines to be published soon would be a better way to move forward.
"There are draft guidelines that are working their way through," he told the View.
"I expect within the next week or so we will have a draft of them at the executive and hopefully ministers can look at a better way through guidelines."
Many obstetricians say a law would offer a mother and themselves better protections. They also say guidelines could work if they were to offer choice, protection and involved clinicians in the decision-making process.
At present, women who have become pregnant as the result of rape, or who are told they are carrying a child that is too ill to survive, are not entitled to a legal abortion in Northern Ireland.
Mr Ford said a change in the law was the only way to resolve the issue so that women in such "dreadful circumstances" could have a termination in Northern Ireland "in a way that I believe a compassionate society should provide".
"It was a complete U-turn from the position that had been previously adopted by Peter Robinson and other members of the DUP when they talked about allowing a free vote on the legislation," he told the BBC's Good Morning Ulster.
"To suggest that guidelines can solve this issue is complete nonsense - guidelines explain the law as it currently stands, and these guidelines have been floating around since 2009 with various legal challenges."
The issue of fatal foetal abnormality came to the fore when Northern Ireland woman Sarah Ewart contacted the Nolan Show to highlight the choice she faced - of either carrying her baby until it died in her womb or travelling to Great Britain where she could access a legal termination.
A year later, in October 2014, the Department of Justice began its consultation, where the public were asked to comment on amending the criminal law on abortion.
In April of this year, the justice committee heard there was substantial support for limited changes to the law, which should also include a conscience clause in the legislation to allow doctors and nurses to opt out of the termination procedure, but not in the woman's aftercare.


Cumbria Police has said it is concerned for the welfare of a mother and her seven-month-old baby who have gone missing.

Donna Newby was last seen at her home address on Rawlinson Street in Barrow shortly before 10:00 GMT on Saturday.
The 33-year-old, described as white, of slim build, with blond hair and about 5ft 4in (1.6m), is believed to have taken baby Corey Coward with her.
She is thought to be wearing a black puffa-style jacket and black trousers.
A force spokesman said: "Police are concerned for her and the child's wellbeing and appeal to anyone who may have seen Donna or Corey to get in touch."


England's fearless approach to their limited-overs cricket makes them a dangerous team in the Champions Trophy, says all-rounder Moeen Ali.

Trevor Bayliss' side go into the tournament, which starts on 1 June, as favourites in a group alongside Australia, New Zealand and Bangladesh.
"The mindset of the players has changed," Moeen said, referring to the influence of captain Eoin Morgan.
"He wants us to play without fear and to hit the lights out."
Since exiting the 2015 World Cup at the group stages, Morgan has led the team to seven wins in nine.
They have defeated New Zealand, Pakistan (twice), Sri Lanka, Bangladesh, West Indies and most recently Ireland. They only lost to Australia and South Africa by the odd game in five.
Much of the credit is given to Morgan and his side's switch from a conservative to an ultra-attacking style of play - England have posted eight scores of 350-plus since 2015 having done so just twice in history before that period.
Moeen, who has scored 1061 runs and taken 44 wickets in his 52 one-day internationals, said: "Morgan is a very calm person which comes across on TV too.
"He hardly panics and is very good at controlling his emotions. He is very relaxed which is good from a player's point of view."
Batsman Joe Root was announced as England Test captain in February to replace Alastair Cook, who gave up the responsibility after a record 59 Tests.
But Moeen believes Yorkshireman Root, who takes charge for the first time in the summer series against South Africa, will make his own mark on the team.
"Joe is quite a cheeky guy and he will bring that personality into his captaincy. He will take more risks as captain than Cook and bring his own style into the side," Moeen, 29, said at a 'NatWest - Cricket Has No Boundaries' event.
"He has been the same since becoming England Test captain. I don't think he is going to change too much, he will be the same Joe Root as he has been for the last three years."
In the limited-overs game, England lost to India in the final of the last Champions Trophy event in 2013, followed by an agonising final-over loss to West Indies in the World Twenty20 last year.
Although they won their first and only ICC global event at the 2010 World T20 against Australia, England have never won an ODI tournament.
Asked if there is pressure being expected to win this time, Moeen replies: "Not really. The team we have at the moment, we deserve that tag. Playing at home is going to make a massive difference and hopefully we can win the trophy.
"We have lost a couple of finals recently but over the last couple of years we have played very well in preparation for this Trophy.
"Hopefully if we get to the final we can overcome the final step and win it. We have gained experience from the T20 World Cup so it will definitely help us."
The Champions Trophy takes place from 1 to 18 June, while Ramadan falls during the same period, starting on 26 May and ending on 24 June.
As the holy month is happening during the British summer, Muslims will be fasting for around 19 hours, with no food or fluids including water allowed to be consumed.
Moeen says he will fast during the matches that are taking place at his home ground of Edgbaston in Birmingham, but will consider whether to do so when travelling to other parts of the country.
He added: "I have to make sure I am hydrated before I begin my fast. My schedule does not change too much but I have to make sure I get a good sleep before the match.
"I have been doing it for a very long time so I am not worried about it. I am used to it and it is more a mental than physical thing."


BBC Sports Personality of the Year will again be saying a big thank you to the UK's sporting volunteers at its star-studded awards ceremony on Sunday, 18 December at the Genting Arena in Birmingham.

The #BigThankYou is Britain's biggest celebration of sports volunteers and recognises the thousands of unsung heroes who give up their time to work tirelessly so others can enjoy many sport and fitness activities.
On the night, live on the red carpet, sporting superstars will surprise volunteers with a phone call to publicly thank them for the contribution they make in sport.
Last year's callers included tennis world number one Andy Murray, golfer Rory McIlroy, international rugby hero Dan Carter, Paralympic tennis star Jordanne Whiley and Olympic medallists Max Whitlock, Greg Rutherford and Dina Asher-Smith.
If you know someone who does that little bit extra to make sport happen, give them a chance to get a call from their sporting hero from the red carpet by nominating them via the Join In website.
Community sports and recreation clubs and groups can be part of the action by celebrating their outstanding volunteers, sharing their stories, posting pictures on social media and thanking them through #BigThankYou.
Former England rugby union player and now sports broadcaster, Maggie Alphonsi, who knows first-hand how important volunteers are to sport, is among the sporting stars backing the campaign.
"My first coach was a volunteer and contributed to my success, helping me to develop my skills," she said. "That made a big difference in allowing me to have the goal to play for England.
"I got into rugby at 14 and the people who kept my club going were all parents and coaches who volunteered, that was really special. When I look back I think, 'wow', if it wasn't for them I probably wouldn't have got into sport and other people wouldn't have got into sport either."
BBC Sports Personality of the Year will be on BBC One on 18 December 2016.
There is a continuing need for more unsung heroes in sport in the UK. If you have been inspired by this and want to get involved in helping grassroots sport in your community, visit the Get Inspired guide to volunteering. There is also a dedicated page for coaching.


One of the UK's leading scientists, Sir Paul Nurse, has proposed giving politicians a greater say in the way scientific research is funded.

It would make science more important at the highest levels of government, says Sir Paul, a Nobel laureate. But he admits that what he is proposing could be seen as "a deal with the devil".
The government spends more than Â£3bn each year on scientific research.
This is allocated by seven specialist research councils, which spend on what they regard as the highest quality research without any government interference.
These range from developing new medicines, hunting for new sub-atomic particles and assessing the impact human activities are having on the environment.
It is a system that has led to the UK being one of the best countries in the world in many areas of research.
But Sir Paul believes it could be better managed if the seven research councils were run by an umbrella body called Research UK.
The aim would be to reduce bureaucracy, increase coordination and develop an overarching strategy for scientific research.
Controversially, Sir Paul believes Research UK should have input from a committee of government ministers.
Critics fear that this might lead to political interference in funding science and the loss of grants for areas of research that may seem obscure now - but could turn out to be scientifically important in the future.
Sir Paul, however, believes that reform is needed to "put science at the heart of government".
Under the current system, the government decides how much to spend on scientific research.
But the scientific community then determines how those funds are distributed.
The so-called "Haldane principle" is that money should be spent on the best science and that decision should be determined by experts in the field.
Sir Paul believes that should continue but a more nuanced approach is now required.
The proportion of money each research council has received has remained more or less unchanged for decades.
But in that time the areas of research that each research council funds, such as physics, biology, medicine, engineering and the environment, have changed dramatically.
It may well be that research in each of these areas has accelerated equally and that it is right that the proportion of funding each receives should remain unchanged.
But the point Sir Paul is making is that even if such an assessment has been made, no-one knows about it.
There is a suspicion from outside that each separate area of the research community jealously guards the money that has been passed on to them for generations.
Sir Paul's concept for Research UK is to create an umbrella body where such discussions can be had openly.
But what about his idea of inviting in the politicians?
He wants ministers with an interest in science to talk to officials at Research UK.
In particular, Sir Paul seems to want the Chancellor to formalise his growing interest in scientific research by chairing the group of ministers.
Is that asking for trouble?
Is there not a danger that ministers will want money spent for new labs in marginal constituencies, pet projects, and funding taken away from areas that don't match current political priorities?
Sir Paul believes they won't and that the scientific community can marshal persuasive arguments.
"Politicians are very sensible people, particularly in this country," he told me.
"We absolutely have to talk to politicians. We, as scientists, cost a lot of money and we have to justify what we do.
"We have to engage with politicians if we are to maintain the support for science which is for the public good and promotes the economy.
"We have to have a proper political discussion - and I want to promote that interface."
Sir Paul is an extremely nice man.
But is he in danger of thinking everyone else is as nice as him and takes the same collegiate, enlightened view as he does of the way the world works?
One concern is that ministers and their mandarins simply don't understand science and that if they are given an inch they will take a mile.
There might be pressure to cut funding for the search of obscure sub-atomic particles, for example in order to spend more on materials science which might have a greater benefit to the economy.
Sir Paul believes that the research community will be able to stand up for itself.
He is clear that he wants the seven research councils to remain as they are - but argues their relative budgets should be reviewed periodically.
"What I am proposing strengthens the research base. To have a more joined-up research strategy.
"So instead of seven individual research strategies we have a combined voice and a proper platform for a strategy.
"I think a good interaction between politicians and scientists is not only good for the scientific endeavour but society."
The elephant in the room is next week's spending review.
Science funding has been relatively protected by George Osborne.
It has been frozen and ring-fenced since 2010 by a Chancellor who has become increasingly amenable to research. He has become convinced that it can be a useful tool for his plans to increase UK productivity.
In order to maintain or possibly improve on the deal they struck five years ago the scientific community will have to give George Osborne something back.
And a little more meddling by the Chancellor may be a price they may well be prepared to pay for a good settlement in the Comprehensive Spending Review.

QPR opened their Championship campaign with a comfortable win against Leeds.

Rangers led early through a scrappy goal from a corner, with Nedum Onuoha appearing to bundle in from a yard out.
Onuoha almost provided a second goal before the interval, but Sebastian Polter saw his low left-footed shot hit a post from the defender's ball in.
Tjaronn Chery's penalty made it 2-0 after Ronaldo Vieira clumsily fouled Jordan Cousins, before Polter fired in a third with the game's final touch.
New Leeds head coach Garry Monk saw his side get off to the worse possible start within four minutes.
The visitors, including former QPR goalkeeper Rob Green on debut, failed to clear a corner and Onuoha was among a number of bodies competing inside the six-yard box for the decisive final touch.
QPR striker Polter caused Leeds' defence problems and twice hit the upright in the opening 45 minutes as the visitors looked off the pace.
Monk's side showed glimpses of an attacking threat in the second half, but £3m summer signing Kemar Roofe was among those who struggled to impose themselves.
Another new recruit, Swedish striker Marcus Antonsson, missed perhaps their best chance at 2-0 behind when he failed to hit the target with a one-on-one against QPR goalkeeper Alex Smithies.
Leeds' misery was compounded with Polter's strike just before full-time, as the German volleyed home from a tight angle.
QPR head coach Jimmy Floyd Hasselbaink: "It was a good start. Perfect? No. But it was a good start as we were organised, had control in the first half and especially in the second.
"Half-time came at the right time for us but then in the second half we controlled it, had more energy and we played really well.
"We only gave away one chance really with our sloppiness and it was a good performance where we can have a look and work on things we need to improve and get better at."
Leeds head coach Garry Monk: "It is obviously disappointing and not the start we wanted.
"But this is just one game and I am confident we have the quality and the character in the group.
"It's a process and I said when I walked in that it's not going to happen overnight. I trust all my players and trust they're good enough and will improve."

Tranmere Rovers moved back up into the National League play-off places with a hard-fought victory over struggling Torquay United.

Gary Taylor-Fletcher smashed home from 30 yards to give the home side a deserved first-half lead.
Rovers doubled their lead with 10 minutes left when James Norwood registered his 10th goal of the season.
Torquay got one back from a late far-post Shaun Harrad header but Rovers held on for a third straight win.


NHS bosses have temporarily halted a decision to award Liverpool community services to an under-performing trust.

It follows concerns over the standard of services at Bridgewater Community Healthcare (BCH) which was rated as "requires improvement".
Labour MP Rosie Cooper had criticised the "staggering" decision to allow BCH to take over services from Liverpool Community Health NHS Trust.
NHS Improvement said the pause was to carry out "detailed assurance work".
The MP for West Lancashire cautiously welcomed what she said was the "right decision".
"There is too much at stake to get this wrong again for the patients and staff involved in Liverpool community health services.
"Commissioners cannot afford a repeat of their previous failures."
Concerns over BCH - which is used by 1.5m people every year - centred on a Care Quality Commission (CQC) inspection last summer.
CQC inspectors measured 40 areas with one rated as outstanding and 27 as good.
But they also found unsafe practice in the management of medication, end of life prescriptions and urgent care centres not following national guidance.
Overall, the trust was given a rating of "requires improvement".
A spokesman for NHS Improvement said it was prudent to order the additional tests to ensure "the proposals remain appropriate."
Colin Scales, chief executive at Bridgewater Community Healthcare NHS Foundation Trust, insisted he is "happy" to provide the "necessary assurance".


Scottish firms raised their selling prices last month at the fastest pace for nearly six years as cost pressures intensified, according to a report.

The latest Bank of Scotland PMI found Scottish business activity returned to growth in December.
But input costs continued to rise, with the rate of inflation quickening to a 67-month high.
Subsequently, output prices increased at their fastest rate since April 2011, the report said.
Service providers linked the rise in input costs to higher prices for food, fuel and timber, while goods producers pointed to the depreciation of the pound.
The December survey of purchasing managers indicated that private sector output bounced back into growth, reaching its highest level for three months.
The expansion was broad-based across Scotland's manufacturing and service sector, with panel members linking this to stronger underlying demand.
The data also pointed to a return to growth in Scotland's workforce numbers, although the rate of job creation remained only moderate overall.
There was also a slight increase in new business during the final month of 2016, ending a two-month sequence of decline.
Nick Laird, from Bank of Scotland Commercial Banking, said: "With output, new orders and employment all returning to growth, and backlogs slowing, Scotland's economy bounced back at the end of 2016.
"The improvement in business conditions across both the manufacturing and service sectors puts Scotland on a firmer footing as we start the new year.
"Headwinds remain, however, principally through the continued increase in input costs, which rose at their sharpest pace for 67 months.
"Given the strain this will place on operating margins, firms throughout Scotland will undoubtedly be looking for this to ease during the year ahead."


Ronnie O'Sullivan says he has no intention of retiring and does not care if he fails to win another World Championship.

The 41-year-old, a five-time winner at the Crucible, was beaten 13-10 by Ding Junhui in a captivating quarter-final.
O'Sullivan was "disappointed" to lose but insisted he enjoyed the tournament and playing in a "fantastic match".
He said: "I love what I do so why would I not do it? The real love is getting your cue out of the case."
But O'Sullivan's season and tournament have been characterised by controversy.
Media playback is not supported on this device
Following his first-round win over Gary Wilson, he claimed to have been bullied by snooker bosses, an accusation strongly denied by World Snooker chairman Barry Hearn.
O'Sullivan's gripes with the sport's authorities date back to January when he publicly criticised a referee and swore at a photographer during the Masters.
That Masters victory was the only tournament win for O'Sullivan this season, although he has made three ranking event finals.
At the Crucible, only Steve Davis, a six-time world champion, and Stephen Hendry, a seven-time winner, have more titles.
And one more ranking-event success would also see him move second on the all-time list with 29, seven behind Hendry.
He said: "I have had the best year of my life and have not won many tournaments, and I think 'how does that relate?'
Media playback is not supported on this device
"But I have never been one for chasing records and I won't stop playing because I am not winning tournaments. I will keep playing because I love playing."
The continued growth of the game in the Far East has also presented O'Sullivan with more opportunities.
"I do a lot of exhibitions," he added. "I like to entertain and put on a good show and I like to enjoy myself. In a world where everything is so serious I like to make it fun.
"China has great offers coming through. I hope to spend a lot of time playing in events. I see myself spending more time in China than I do here."
Meanwhile, Hearn - who said O'Sullivan's claims of "bullying and intimidating" were words that were "alien" to him - announced an increase in tour prize money for next season, going up up £12m from the current £10m, with an aim to reach the £20m mark.
The winner of the 2017 World Championship will receive £375,000. That will rise to £425,000 in 2018 and £500,000 the following year.
Hearn also said entry fees for playing in ranking tournaments would be abolished for tour players.


A man who pledged to run 401 marathons in 401 days has resumed the challenge after 11 days off, recovering from a back injury.

Ben Smith, 34, had completed 284 consecutive marathons in 284 days when he developed an umbilical hernia, in Aberdeen, on 10 June.
He set off from Inverness at 10:00 BST after medical care and following advice to "take time out and recuperate".
Mr Smith said he would use "everything in his power to be back on the road".
Since 1 September 2015, he had run 284 consecutive marathons in 284 days, covering 7,440.8 miles across 222 different locations across England, Wales and Scotland.
He said he would now need to cover an extra 2.5 miles a day for the next 106 days to make up for the time lost through injury - missing 10 days of running equates to 262 miles.
He said: "I was very upset the challenge had to be suspended especially when you think of all the hard work myself and the 401 team have put in over the last three years.
"Today I am feeling positive in both my mental and physical state and will no doubt use everything in my power to be back on the road."
He praised the "amazing" 401 team and said they would "deliver all the objectives we set out to do".
Mr Smith hopes to raise Â£250,000 for the anti-bullying charities, Stonewall and Kidscape.
The aim is to finish the run as planned on 5 October in Bristol.


The Belfast Giants' hopes of catching Elite League leaders Cardiff Devils suffered a major setback with Friday's 5-2 home defeat by Sheffield Steelers.

The Devils remain five points ahead of the Giants with one game in hand.
Belfast host Coventry in their final home fixture of the season on Saturday, and then face the Devils away twice.
Mathieu Roy (2), Markus Nilsson, Geoff Walker and Guillaume Desbiens scored for Cardiff, with Jerome Leduc and James Desmarais netting for Belfast.
The result means Cardiff Devils will win the Elite League for first time in 20 years if they win at Sheffield on Saturday.
After a scoreless first period, the Steelers led 2-0 at the conclusion of the second period thanks to goals from Roy and Nilsson.
Leduc pulled one back, but strikes from Walker and Roy's second extended the visitors' advantage, before Desmarais scored.
Desbiens made the victory secure for the Steelers, who now move above their opponents in the league standings.


The family of a man killed in a crash with an 87-year-old who was travelling the wrong way on the M1 have called for older drivers to be retested.

Michael Luciw, 27, from Nottingham, was a passenger in a van that was hit by a Mazda Premacy, being driven the wrong way on the motorway by Albert Kenneth Newman, who also died.
Mr Luciw's family said retired people should undergo regular driving tests.
Age UK said it was "vital" older people could drive for as long as possible.
The family described Mr Luciw, the father of a baby girl, as generous, kind-hearted and a lover of practical jokes.
"He had only just turned 27 and he had his whole life ahead of him," said his mum Andrea Shelton.
"He was looking forward to his baby's first crawl. Now he will miss all of her life through no fault of his own."
"It doesn't feel as if we have lost him - it feels as if he has been taken away from us," said Mr Luciw's brother Simon.
"There are so many things that should be put in place so things like this could be avoided. People are driving that shouldn't be on the road.
"The older you get, the more your reactions slow down.
"There needs to be some sort of test introduced, in a car with a driving instructor, so you get a true reflection of how good a driver you are.
"You get a free bus pass once you are in your 60s so people can't say they are going to lose their freedom if they have their licence removed."
Mrs Shelton said Mr Luciw, a delivery driver, was on a long-distance journey with a colleague Andy Harrington when the crash happened at 02:00 GMT on 12 October near Kegworth, Leicestershire.
Mr Newman's car was heading north on the southbound carriageway.
Mr Harrington, who was driving the Ford Transit, said he had not seen Mr Newman's car until the last second.
"I managed to swerve slightly towards the crash barrier but there was nothing I could do," he said. "You couldn't even blink that fast.
"It lives with me. I still get sleepless nights. It's not something I will ever forget."
Mr Harrington, who sustained serious injuries in the crash, said retired drivers should have to undergo medical examinations.
"It's up to the government whether they listen to us," he said. "But if that driver hadn't been on the road that morning, Michael would still be here with his daughter."
Currently drivers over 70 in the UK must fill in a self-assessment form every three years to renew their licences. The form does not include a medical or driving test.
The Driver and Vehicle Licensing Agency (DVLA) which maintains the database of registered drivers said it had no plans to restrict licensing on the basis of age.
"Evidence does not show that older drivers are more likely to cause a serious accident than others," it said.
"The rules are clear that all drivers over 70 have to renew their licence every three years and have to tell DVLA about any medical conditions which might affect their driving.
"If we find evidence a driver does not meet the appropriate medical standard we immediately remove their entitlement to drive."
Caroline Abrahams, charity director of Age UK, said: "We know driving often allows older people to have the independence to get out and about, go shopping and attend appointments so it's vital that older people are supported to continue driving safely for as long as possible."
