Jeremy Corbyn will not campaign for Britain to leave the European Union, the new Labour leader tells the BBC in a wide-ranging interview.

The new Labour leader Jeremy Corbyn faces David Cameron in his first Prime Minister's Questions since taking on the role.

Labour leader Jeremy Corbyn tells the BBC's Laura Kuenssberg that he will not campaign for Britain to leave the EU.

This from BBC political editor Laura Kuenssberg after her interview with Jeremy Corbyn,

Jeremy Corbyn has told the BBC that he will not campaign for Britain to leave the EU. The Labour leader said this is a "developing position" but that he could not foresee a situation where Labour under his leadership would campaign for "Brexit". On his decision not to sing the national anthem he said it was, "very strange" that his decision had attracted so much interest. On his shadow cabinet disagreeing with him publicly he said there will be discussions ahead, that he asks colleagues to respect his mandate and that the final decision on policy will be his.

Pundits have been discussing Jeremy Corbyn's PMQs debut. Anne McElvoy, of the Economist, says his tactics weren't bad, but:

The Guardian's Polly Toynbee says it was Mr Corbyn's chance to say "here I am, this is me" and he did that to good effect. She adds: "He didn't have that look of panic that poor Ed Miliband often had."

Former Labour foreign secretary Margaret Beckett says Jeremy Corbyn "wrong-footed" David Cameron with his Prime Minister's Questions tactics.

Shadow Northern Ireland secretary Vernon Coaker has distanced himself from remarks made by shadow chancellor John McDonnell in 2003 when he called for IRA terrorists to be "honoured". Mr Coaker told PM:

New shadow health secretary Heidi Alexander has invited Daily Mail columnist Sarah Vine to join her on a 5k run this weekend after the journalist wrote in the paper, external that the MP "looks like she needs to lay off the hobnobs". Ms Alexander, who admits on her twitter account that she is "not great at twitter or diets but currently trying my best at both", responded:

Bank of England Governor Mark Carney has been asked, in a round-about way, about the new Labour leader's policy of "people's quantitative easing" - that is his idea of effectively asking the central bank to print money to pay for investment in national infrastructure. At a meeting of the Treasury select committee, Tory MP Steve Baker criticised the Bank's existing policy of QE - focused on helping stimulating consumer spending and boosting the economy - saying it had skewed asset prices, widened inequality and led to a situation where the "political radicalism" of the new Labour leader was seen as a "credible strategy". Mr Carney, giving what he said was a personal view, said there were a number of "fundamental structural drivers" behind income inequality in advanced economies. These, he said, should be dealt with through a "concerted" range of policies but that "monetary policy is not part of that response". The goal of monetary policy, he insisted, was about keeping prices "low, stable and predictable". He added:
