Intruder interrupts hearing and throws foam pie at Murdochs

Ten members of Met Police have worked for News International

19.20: Questioning ends. Rebekah Brooks tells MPs she would like to come back to answer more questions once she is "free from legal constraints". Brooks concludes: "I know you've heard unreserved apologies from Rupert and James Murdoch. I just want to reiterate my own. The most important thing that I feel going forward is to discover the truth behind the allegations, particularly for the family of Milly Dowler."

19.07: Brooks: "I went to Downing Street regularly while Brown and Blair were at Number 10". She adds: "Strangely it was while Labour PMs were in Downing St that I went regularly, not under the current administration".

19.01: Brooks says she did not know that Neville Thurlbeck was an alleged "informant to police".

18.55: Brooks is questioned about her communications with Scotland Yard regarding the case of Dave Cook, a policeman allegedly put under surveillance by NoW. On 5 July, Channel 4 News reported that Brooks had been informed of the allegations at the time in 2002.

Brooks tells MPs: "My recollection of that meeting was entirely different... on a completely different subject. They [Channel 4 News] say it was a meeting in November.. I checked my diary as much as possible and there was no meeting in November, however there was a subsequent meeting in very early January.

"On the other hand because of my Sarah's Law campaign I did have some pretty regular meetings at Scotland Yard, mainly with the paedophile unit."

18.50: Brooks: "[Phone intercepting] was not a practice that was condoned or sanctioned under my editorship."

18.30: A row erupts involving former NoW editor and US TV presenter Piers Morgan after committee member Louise Mensch alleged the CNN anchor had written in his book about using phone tapping to "get scoops". Mr Morgan said this was a lie and demanded an apology. They later clash on US television, with Morgan calling Mensch a "coward" for refusing to repeat the claim without the protection of parliamentary privilege - watch here.

18.28: Brooks: "The Milly Dowler story went on for many years. What you are asking me is when did I first hear that [her] phone had been intercepted? The first time I heard that was two weeks ago."

18.15: Brooks says when Andy Coulson left NoW he had an agreement his legal fees would be paid and it was the same for Clive Goodman.

18.10: Rebekah Brooks says she has never "knowingly sanctioned" a payment to a police officer.

Conservative Party statement:
"There have been some questions about whether the Conservative Party employed Neil Wallis.
"We have double checked our records and are able to confirm that neither Neil Wallis nor his company has ever been contracted by the Conservative Party, nor has the Conservative Party made payments to either of them."It has been drawn to our attention that he may have provided Andy Coulson with some informal advice on a voluntary basis before the election. We are currently finding out the exact nature of any advice.
"We can confirm that apart from Andy Coulson, neither David Cameron nor any senior member of the campaign team were aware of this until this week."

18.00: It is reported by the BBC that Neil Wallis (former deputy NoW editor) was informally advising Andy Coulson before the general election.

17.50: Tom Watson asks Brooks "how extensively" she worked with private detectives during her time as editor of The Sun and the News of the World. She says the use of private detectives in the late 1990s "was a practice" but after the "What price privacy?" report it was stopped. She concedes that NoW used private investigators but will not say if she personally approved payments to them.

He concludes: "Invading privacy is wrong, paying police is wrong, neither has any place in any part of the company I run. No excuses. This is why News International is cooperating to see that justice is done."

17.22: Louise Mensch, a Conservative MP, asks if Rupert Murdoch has considered resigning as CEO of News Corp. He says "no" adding that "I am the best person to clean this up".

17.10: The hearing gets under way again with MPs thanking the Murdochs for agreeing to continue.

16.55: The hearing is interrupted. An intruder with a plate of foam lunges at Rupert Murdoch. Mr Murdoch's wife Wendi Deng jumps up to defend her husband, slapping the attacker away. As the man - named as comedian Jonnie Marbles - is led away, Deng throws the empty plate at him.

16.05: Both Murdochs are initally elusive on the subject of whether convicted phone hacker Glenn Mulcaire (whose detailed notes have revealed the wide scope of possible victims) has had his legal fees paid by News Corp.

James Murdoch then says he was "surprised and shocked" to learn some fees have been paid.

Murdoch Senior says he would ask for any payments to Mr Mulcaire to stop, providing it did not breach any legal contract. Biographer Michael Wolff tweets "Okay, they paid, they paid Mulcaire".

13.26: Sir Paul: "I sincerely regret that Mr Yates has gone. But the Met will recover. I sincerely regret going. I do think we need to handle the media differently in the future".

"This is almost certainly my final public appearance after 36 years of service. But I am not leaving because I was pushed. I'm going because I'm a leader.

"Leadership is not about popularity, it is about putting your organisation first."

This is almost certainly my final public appearance... but I am not leaving because I was pushed. I'm going because I'm a leader. Sir Paul Stephenson

13.22: Sir Paul: "When people are asking if I supervised John Yates... he is a senior police officer... "

13.00: Chris Herbert, editor of Jane's Police Review, tells Channel 4 News: "He's certainly under severe pressure due to the weight of innuendo and implied wrongdoing being brought forward.

"Hindsight is a useful tool though and we're looking at decisions made two years ago in light of information that is only known now. As commissioner there's no way he could possibly have known everything that goes on in a force of 50,000 people - you rely on your advisers and officers all the way down the management chain."

12.55: Sir Paul tells MPs that £1000 per day for Wallis's services was the "cheapest available". Read more on Neil "Wolfman" Wallis

12.50: Sir Paul says "I never Met Mr Wallis and Mr Coulson together" but agrees the pair must have talked once Coulson was working for PM. He adds: "It is a distortion to say that Mr Wallis worked for me [in the way that Coulson worked for David Cameron at Number 10]".

12.43: On the matter of lunches and dinners with NoW execs, Sir Paul says it was not down to him that the News of the World was so "dominant in the market" but because of this it was right that he held regular meetings with executives from the paper.

12.40: Responding to David Winnick MP, Sir Paul says it was "damnably unlucky" that Neil Wallis was connected to Champneys.

At the time the spa's public relations were being handled by a company whose managing director was Neil Wallis.

12.35: Sir Paul Stephenson tells MPs "when I took over as prime minister...". Chuckles all round before the outgoing Met chief corrects himself.

12.10: Sir Paul responds: "I am not apologetic over Champneys. The mayor and Home Secretary Theresa May accepted my [resignation] very reluctantly. So did my wife."

12.05: Sir Paul Stephenson, outgoing commissioner of the Metropolitan Police begins giving evidence to the Home Affairs Select Committee. Sir Paul resigned on Sunday after revelations about his links to Neil Wallis, a former News of the World deputy editor who was arrested last week over hacking.
