Jeremy Corbyn repeatedly floundered when asked how much a flagship new childcare policy would cost in a hard radio interview. It is not good enough that a prospective prime minister should be so cavalier about his plans to spend other people's money.
Jeremy Corbyn has finally coughed up the figures on how much Labour's free child care policy will cost.
Earlier, Corbyn was unable to provide the figure during an interview with BBC Radio 4's Woman's Hour.
The London School of Economic's Dr Bart Cammaerts, who studied coverage of Corbyn in the United Kingdom press, said he was "delegitimised as a political actor" from the moment he became a candidate in the 2015 Labour leadership contest.
Jeremy Corbyn: It would cost...um, it would obviously cost a lot to do so, we accept that.
There were 239,700 tweets sent about Mr Corbyn - compared with 107,800 for the Prime Minister - over the 90-minute period, during which the pair were questioned by a studio audience and Jeremy Paxman.
"Because since the very moment the British people took that momentous decision, it was clear to me that it was not just a vote to leave the European Union".
Asked during his time The One Show sofa if he and his wife Laura Alvarez divided housework along gender lines, Corbyn simply shook his head.

Corbyn: All of our manifesto is fully costed and examined. The point I'm trying to make is that we're making it universal so that we are in a position to make sure that every child gets it.
A spokesman for Mr Corbyn said: "Theresa May floundered on her record on police cuts, on funding for our NHS and schools and on her manifesto policy on social care that didn't last more than a few days before it was amended with an unspecified cap".
"All this raises, in our view, a number of pressing ethical questions regarding the role of the media in a democracy".
The Labour leader said he did not believe it had been a "plot" but added: "Margaret Thatcher made a great deal of that issue at the time".
During the interview Mr Corbyn also rejected Theresa May's approach to domestic chores, denying that there were "boys' and girls' jobs" in his household.
It also makes the prospect of a coalition between Labour, the Scottish Nationalist Party (SNP) and Liberal Democrats a realistic possibility, for the first tiime in this election campaign.
Earlier, a separate survey by YouGov found that Labour's lead among voters under 50 is growing after the Tories' revealed unpopular social care policies for pensioners.
