The UK and the EU will begin negotiations on food and drink and emissions trading deals next week.
It comes after Keir Starmer and European Commission president Ursula Von der Leyen reiterated the need to quickly implement the post-Brexit reset deal following a call on Wednesday evening.
The Prime Minister said “any deals must result in tangible benefits to the British public,” according to a No10 read-out of the call.
While Von der Leyen said work was ongoing to reach “a mutually beneficial outcome” on the UK's access to Brussels' flagship Security Action For Europe (SAFE) defence scheme.
Naomi Smith, chief executive of Best for Britain, said:
“These talks are vital to cutting costs at the checkout and reducing energy bills for both Brits and people in the EU, so this progress is welcome.
"Recognising the tangible benefits of closer EU-UK alignment, both sides must now act swiftly to make it a reality.”
