London (CNN) Britain's Brexit journey has been plagued by uncertainty -- but on Wednesday we might get the answer to these two questions: Firstly, can Prime Minister Theresa May put her deal and the stability of the country ahead of her political career and pledge to step down as leader to secure those two things? Secondly, can the UK Parliament find an alternative plan to help Britain leave the EU under different terms?

On the first, as part of a political plea bargain, Conservative Brexiteers will this evening urge the Prime Minister to set a timetable for her departure from Downing Street in exchange for their votes.

May has so far insisted she will not announce her resignation -- a position in keeping with her steadfastness and, at times, intransigence in office.

But should May decide to hint at her resignation, she could gain majority support in Parliament for her Brexit plan, nearly five months after it was agreed with Brussels and after weeks of argument and successive defeats.

Britain's Prime Minister Theresa May leaves 10 Downing Street in London on March 25, 2019.
