Jeremy Corbyn coming to power in Britain would be a "very dangerous experiment", Tony Blair has suggested.

The former Labour prime minister said populist politicians such as Mr Corbyn, whether on the right or the left of the political spectrum, were "worrying".

Speaking in an interview with BBC2's This Week's World, Mr Blair refuted the suggestion that his unpopularity helped paved the way for Mr Corbyn's rise to become Labour leader.

He said: "It's a big challenge for the centre and when I'm not thinking about the Middle East, I'm thinking about this because I do think, by the way, it would be a very dangerous experiment for a major western country to get gripped by this type of populist policy making - left or right, a very dangerous experiment."

Mr Blair famously said last summer that anyone thinking of voting for Mr Corbyn as Labour leader because it was what their heart told them to do should "get a transplant".

The former Labour leader also said that he had to make tough decisions about the controversial 2003 Iraq invasion - an episode that made him deeply unpopular.

"I have a real humility about the decisions that I took and the issues around them," he said.

"I was trying to deal with this in the aftermath of 9/11 and it was very tough, it was very difficult. I think it's important that we also have humility then about the next phase of policy making, so we try and actually learn the lessons of the whole period since that time."

Sir John Chilcot, chairman of the inquiry into the Iraq war has revealed that the report will be published in June or July 2016.
