The UK's former chief negotiator in the Brexit process, David Frost, has been appointed to the British Cabinet as a Minister in charge of Britain's relationship with the EU.

He is to replace Michael Gove as the UK chair of the Joint committee, the body that sorts out disputes arising under the Withdrawal agreement - including the Northern Ireland Protocol. 

He is also taking over the UK chair of the Partnership Council, which governs the future relationship agreement between the EU and the UK. 

The EU chair of both bodies is Commission vice President Maros Sefcovic. 

A former diplomat, Mr Frost was appointed to the House of Lords last year. 

From 1 March he will become a Minister of State in the Cabinet Office, and will be a full member of the Cabinet. 

In the new role he will lead the UK's institutional and strategic relationship with the EU. 

He has also been tasked with "driving through changes to maximise the opportunities of Brexit, including on international trade and economic issues". 

This will include coordinating relations with the EU institutions and the 27 member states.
