Prime Minister Boris Johnson has replaced Amber Rudd only hours after she stunned Westminster by quitting
Therese Coffey MP, an environment minister and MP for Suffolk Coastal, has been promoted to Work and Pensions Secretary.
Elected in 2010, Ms Coffey is a former deputy Commons leader and was appointed as environment minister by Theresa May.
The devout Liverpool FC fan backed Remain during the EU referendum in 2016.
Her predecessor Ms Rudd resigned after suggesting the Government was aiming to take the UK out of the EU without a deal.
Speaking on the BBC's Andrew Marr Show, she said she was shown a "one-page summary" when asked for evidence of the Government's work in negotiating a deal with the European Union.
She said: "I have not seen enough work going into to actually trying to get a deal.
"When I asked Number 10 for a summary of what the plan was for actually getting a deal, I was sent a one-page summary."
On Ms Rudd's departure, former Conservative cabinet minister and independent Justine Greening told Sky News's Sophy Ridge on Sunday: "She's been clear that there isn't really a negotiation going on with the EU to try and get any kind of Brexit deal and, from my perspective, I'm waiting to see the Prime Minister get on a plane to Brussels.
"That's not happened yet and so my concern's always been that there isn't really a negotiation happening on Brexit now and therefore the main objective of the Government is to leave with no-deal."
