Foreign Office Minister Sir Alan Duncan has resigned from the government

Sir Alan Duncan has become the first minister to quit the government ahead of an expected Boris Johnson win in the Tory leadership contest tomorrow.

The former Minister for Europe and the Americas has been a vocal critic of Johnson, who used to be his boss as Foreign Secretary until 2018.

Several Tory MPs are expected to resign from their government posts if Johnson is confirmed as the next Prime Minister.

Speaking on Marr yesterday, the Chancellor Philip Hammond said he would resign ahead of a Johnson premiership. Justice Secretary David Gauke is also expected to quit. Both men have expressed concern over Johnson’s Brexit plan, specifically his ‘do or die’ approach to leaving the EU deal or no deal on 31st October.

The new Tory leader will become Prime Minister on Wednesday 24th July after Theresa May’s final performance at PMQs.
