South West Surrey MP Jeremy Hunt has been appointed the new Foreign Secretary after Boris Johnson quit.
The prominent leave campaigner told Theresa May the Brexit dream was dying under her watch, but his successor, who used to be Health Secretary, says he's backing her completely:
"My principle job, at a time of massive importance for our country, is to stand four-square behind the Prime Minister so that we can get through an agreement with the EU, based on what was agreed by the cabinet at Chequers.
"Part of that is making sure Britain remains strong and confident."
Mr Hunt tweeted his reaction to the announcement, in which he also mentioned his reluctance to move on from his role as Health Secretary.
He's been replaced in that job by Matt Hancock.
Huge honour to be appointed Foreign Secretary at this critical moment in our country’s history. Time to back our PM to get a great Brexit deal - it's now or never...— Jeremy Hunt (@Jeremy_Hunt) July 9, 2018
Massive wrench for me to leave health - I know some staff haven’t found me the easiest Health Sec but the NHS, and particularly patient safety, has become my passion & it really was the greatest privilege of my life to serve for so many years— Jeremy Hunt (@Jeremy_Hunt) July 9, 2018
Couldn’t ask for a better successor than @matthancock to take forward long term NHS plan with his brilliant understanding of the power of technology. The new NHS app will be in safe hands!— Jeremy Hunt (@Jeremy_Hunt) July 9, 2018
Three junior ministers have also resigned.
Meanwhile, Dominic Raab has replaced David Davis as Brexit secretary after he walked away on Sunday.
