Davis, who has been leading the UK government’s negotiations to leave the EU, announced his departure on Sunday night (July 8).
It was reported two junior ministers at Davis’s Department for Exiting the EU also resigned, Steve Baker and Suella Braverman.
However, it was confirmed on Monday (July 9) Braverman would remain in post.
It comes after Prime Minister Theresa May’s Brexit summit at Chequers on Friday (July 6), during which the cabinet agreed an outline "soft Brexit" plan - which includes a "mobility framework" to support movement within the EU.
