British Foreign Secretary Boris Johnson speaks ahead of Prime Minister Theresa May during her last campaign visit at the National Conference Centre on June 7, 2017 in Solihull, United Kingdom.

While no challenge has yet materialized, the prime minister will have to conduct a leadership contest if her own lawmakers move against her with the necessary support. That process involves at least 48 politicians sending letters calling for a vote of confidence to a powerful group of backbenchers known as the 1922 committee.

May, however, directly addressed that committee last night and she reportedly received thunderous support from lawmaker’s keen to back her latest plan.

Speaking to CNBC’s “Street Signs” Tuesday, the U.K.’s former Defense Secretary Michael Fallon said May was in a stronger position as she was now presiding over a more unified cabinet.

“Nobody has come up with a better plan in two years so as tumultuous as it has been, the air has been cleared now and we go forward with that agreed plan which now goes to Brussels,” he said.

A more detailed version of the U.K.’s position is due to be published this week. It is this document, known as a White Paper, that will form the basis of Britain’s negotiating stance. Fallon said Brussels would now have to respond.

“The ball is in Europe’s court. It is now up to the EU to respond and I hope they will show some flexibility,” he said.
