Speaking outside Parliament, Jacob Rees-Mogg said that the UK needs a leader who will stand up to the EU.

Tory Brexiteer MP Jacob Rees-Mogg has called for a leadership contest to oust Theresa May.

Speaking outside Parliament, he said that the UK needs a leader who will stand up to the EU.

Earlier, a spokesperson for a group of Conservative MPs said that Jacob Rees-Mogg is submitting a letter of no confidence in Prime Minister Theresa May.

It follows Mr Rees-Mogg asking Ms May whether he should instigate a leadership challenge, as MPs heard Tory opposition to the Brexit deal was “going up by the hour”.

Speaking in the Commons earlier, chairman of the European Research Group Mr Rees-Mogg said:

“As what my right honourable friend says and what my right honourable friend does no longer match, should I not write to my right honourable friend the member for Altrincham and Sale West?”

This was a reference to Sir Graham Brady MP, the chairman of the Tory 1922 committee, to whom MPs must write to express no confidence in a leader in order to trigger a challenge.

Mrs May replied that “some difficult choices have had to be made” to avoid a hard border on Ireland, adding:

“It is not only our intention, but we will be working to ensure that protocol does not have to be put into place.”

Within the Conservative Party, a challenge is triggered if 15% of Conservative MPs write letters demanding a confidence vote to the chairman of the party’s “1922 Committee”.

The Conservatives have 315 MPs, so 48 would need to write such letters for a vote to be called which represents MPs who have no government jobs.

In the event of a leadership contest, all Conservative MPs can vote for or against their leader.

If May wins, she remains in office and cannot be challenged again for 12 months.

If she loses, she must resign and is barred from standing in the leadership election that follows.
