Theresa May was said to have had tears in her eyes as she was told MPs have run out of patience for her to announce her departure date.
The Prime Minister has been fighting to keep her Brexit deal alive and prolong her position, but her grip on power has weakened.
She has been told she must go by June 30 at the latest so that the Tories can hold a leadership election. Campaigning for that job has effectively already begun with Boris Johnson announcing on 16 May that he would ‘go for it’.
She met with senior members of the 1922 Committee of Tory MPs in what has been described as an ’emotionally-charged’ meeting yesterday.
Mrs May’s chances of receiving Labour support for the Withdrawal Agreement Bill (WAB) appear to be fading, with Jeremy Corbyn’s party frustrated at the lack of progress in cross-party talks and the prospect of a new prime minister tearing up any compromise.
On 17 May, Mr Corbyn told Mrs May that the cross-party Brexit talks have ‘gone as far as they can’ and ‘we have been unable to bridge important policy gaps between us’.
In a sign the negotiations are foundering, Mr Corbyn said he found it hard to deal with a Government in ‘disarray’ and warned ‘the time limit is very soon’. But Number 10 insisted the talks process, which began in early April, remained alive.
There were meetings between officials on 16 May and the prospect of the talks collapsing was ‘not how I see it’, a senior source said.
Meanwhile, European Commission president Jean-Claude Juncker has spoken of his regret at not speaking out during the campaign about Vote Leave’s campaign claim that the UK sends the EU £350 million a week.
In an interview with Austrian paper Der Standard, he said: ‘I think it is an incomprehensible error on my part that I did not intervene in the Brexit campaign owing to British wishes.
‘So many lies were told, so many of the consequences of a ‘no’ were misrepresented, we as a commission should have spoken up.’
The Prime Minister will meet the chairman of the Tory backbench 1922 Committee Sir Graham Brady at the start of June to agree to the details of the leadership contest to succeed her.
The move follows a lengthy meeting on 16 May between Mrs May and the 18-strong 1922 executive during which she again came under pressure to name her exit date from Downing Street.
Even as the summit was taking place in Westminster, former foreign secretary Boris Johnson galvanised the race to succeed her, confirming he would be a candidate.
