Tony Blair's evidence to the Leveson Inquiry was interrupted today when a protester burst in and yelled "this man should be arrested for war crimes".

The man, who somehow managed to evade security, was swiftly removed from the court room after causing the disturbance and Lord Justice Leveson ordered an immediate inquiry into how he had got in.

He said: "I would like to find out how this gentleman managed to access the court through what's supposed to be a secure corridor and I'll have an investigation undertaken about that immediately."

Earlier, Mr Blair today told the inquiry into press standards that he had a "working relationship" with media mogul Rupert Murdoch when in office.

Mr Blair told the Leveson Inquiry he "got to know Mr Murdoch better" after leaving office in 2007.

He said when he was Prime Minister his relationship with Mr Murdoch was "about power" but was not personal.

Mr Blair insisted he had never agreed to any pact with any media organisation.

"There was no deal on issues to do with the media with Rupert Murdoch, or indeed, anybody else, either expressed or implied and to be fair, he never sought such a thing."

He added: "When it came to the specific issue in relation to the Murdoch media group, we more often decided against them than in favour."

Mr Blair was quizzed about his now notorious trip to Hayman Island, Australia, in 1995 where he addressed News Corp executives.

Asked if he agreed with the views of then Australian prime minister Paul Keating, who according to Alistair Campbell's diaries said Mr Murdoch was a "big bad bastard" and the only way to deal with him was to act the same, Mr Blair said he "didn't quite buy the crudeness" of that assessment.

He added: "I came, in time, to have a different view myself."

Mr Blair said his speech focused on elements he knew the organisation would want to hear mixed in with wider policy arguments.

He added: "I would not have been going all the way round the world if it had not been a very deliberate and very strategic decision that I was going to try to persuade them, and I had a minimum objective."

He added: "The minimum objective was to stop them tearing us to pieces and the maximum objective to open the way to support."
