Theresa May is having a tough time holding her government together.
Mr Johnson's almost two years as foreign secretary was not without controversy, with the ambitious Tory heavyweight having been accused of undermining Mrs May on more than one occasion - and making headlines for other reasons.
Like her Conservative predecessors, Theresa May has had the impossible task of balancing the demands of those in her party who want a clean break from the European Union and those who want a close relationship after Brexit.
At 3pm on Monday, a statement was issued by Downing Street to say: "This afternoon, the Prime Minister accepted the resignation of Boris Johnson as Foreign Secretary".

Fianna Fail's Brexit spokesperson Lisa Chambers said the double resignation was of "grave concern" but urged the British Government to continue with its plan to publish the white paper this week.

At a Cabinet meeting Friday, May demanded members support a plan for Brexit that it would include Britain partly remaining in the single market and signing up to a "common rulebook" for goods. Gauke said. "The challenge is all very well for people to say I wouldn't do this".
"With her Government in chaos, if she clings on, it's clear she's more interested in hanging on for her own sake than serving the people of our country", he said.
