Who's in line to take over from David Davis as Brexit Secretary?

David Davis's departure as Brexit Secretary leaves a major position in Theresa May's Government vacant. Here is a look at some potential successors:

Michael Gove

The Environment Secretary is a prominent Brexiteer and - hours before Mr Davis's resignation - on Sunday urged fellow Tories to get behind the Prime Minister and her Brexit plan agreed at a Chequers summit on Friday.

Mr Gove would likely be a contender in any future leadership contest, which could influence his decision on whether to spearhead Mrs May's plans for Brexit.

Boris Johnson

The Foreign Secretary backed the proposals at Chequers despite claiming that defending the plans during the meeting was like "polishing a turd".

Like Mr Gove - who infamously made a rival bid for the leadership after the referendum - Mr Johnson has long been suspected of aiming to lead the party and be prime minister.

Backing Mrs May's proposals could affect his support among Eurosceptic backbenchers.

David Lidington

The Cabinet Secretary is effectively Mrs May's deputy and has previously held the position of Europe Minister in the Foreign Office.

The MP for Aylesbury campaigned to remain in the European Union.

A former justice secretary, Mr Lidington took over as Cabinet chief from Damian Green after he was sacked over a computer porn scandal.

Robin Walker

The MP for for Worcester is one of two ministers left in post at the Department for Exiting the European Union (DExEU) after the resignations of Mr Davis, his deputy Steve Baker and the reported departure of Suella Braverman.

Mr Walker campaigned for Remain in the referendum.

Lord Callanan

The second minister reported to remain at (DExEU) was an MEP for the North East of England. He also led the European Conservatives and Reformists group from 2011 to 2014.
