British Prime Minister Theresa May's changing Cabinet

Boris Johnson resigned as UK foreign minister on Monday, the second resignation from Prime Minister Theresa May's Cabinet in less than 24 hours. The conservative had been a key face for the Leave campaign ahead of Britain's 2016 referendum. He seemed to quit in protest at May's plans to push through a "soft Brexit." May's position seemed fragile even before two key ministers quit.

Citing disagreement with the prime minister over EU divorce talks, Brexit Secretary David Davis quit his post late on Sunday. Davis, who served as UK's top Brexit negotiator, said Theresa May's policy could leave the UK in an "inescapable" negotiating position.

In April 2018, Home Secretary Amber Rudd resigned when reports surfaced of UK authorities mistreating long-term British residents from the Caribbean. The officials wrongly labeled the so-called "Windrush Generation" as illegal immigrants. London originally invited the migrants to help rebuild UK economy after World War II, with the ship "Windrush" transporting the first group to the UK shores.

Michael Fallon stepped down as British defense secretary in November 2017 after apologizing for touching a journalist's knee in 2002 and other allegations of inappropriate conduct that have not been made public. In his letter of resignation, Fallon said he had "fallen short of the high standards" expected of the military. Fallon was replaced by Gavin Williamson, one of May's trusted allies.

International Development Secretary Priti Patel also reigned in November, after being found to have had 12 undisclosed meetings with officials in Israel, including with Israeli Prime Minister Benjamin Netanyahu, in breach of diplomatic protocol. Patel discussed the possibility of British aid being used to support medical assistance for Syrian refugees arriving in the Golan Heights.

First Secretary of State Damian Green was forced to resign after an inquiry found he made misleading statements about pornographic material found on a computer in his parliamentary office in 2008. A key ally of Prime Minister Theresa May, he was named secretary of state after May lost a parliamentary majority in early elections. Green was among those who urged Britons to vote to say in the EU.

Jo Johnson, the the Remain-backing younger brother of Boris Johnson, quit May's government in November over her "delusional" Brexit plans. Johnson said the withdrawal agreement being discussed by the European Union and British leaders would be a "terrible mistake" that would leave Britain weaker economically and with "no say" in EU rules it must follow, and years of uncertainty for business.
