On January 29 Tony Blair gave evidence to the Iraq inquiry.

Two days before Lord Goldsmith, attorney general at the time of the war, was questioned for a whole day too.

He appeared two days before Blair, and was questioned in detail about the legality of the conflict and, in particular, about his decision to change his legal advice within the space of 10 days in March 2003.

His original advice included caveats about the legality of the war, but these were omitted when he later told the cabinet he was confident the war was legal.

Tony Blair was questioned for three hours in the morning and three hours in the afternoon.

The inquiry finished with him taking responsibility but he had no regrets of taking Saddam Hussein out of power and he thought he was a monster.

As he exited the inquiry he was booed by the spectators and one of the spectators shouted at him “You are a liar” and “You are a murderer.”

After Tony Blair tried to exit the building had to go into lockdown because the protesters tried to enter the building using every entrance.

Eventually the protesters gave up because there were too many police guarding the building.

The BBC interviewed one of the protesters who was one of the spectators in the inquiry. He said: “I think they let him get away with it because they went too easy on him, also they were a bit ignorant on what questions they asked Tony Blair and weren’t asking him the more important questions.”

The BBC also got a comment form another protester saying that they want him to have criminal charges for sending the country to an "illegal war".
