The Prime Minister reportedly does not want talks to continue past September because it will leave businesses with little time to get ready for the end of the transition period in December. This comes as Downing Street confirmed that the UK’s chief Brexit negotiator will take on his new position as Mr Johnson’s national security adviser at the end of August.
Although his role as negotiator will not be replace, Mr Frost has said that Brexit talks will remain his top priority “until those negotiations have concluded”.
A spokesperson for the Prime Minister indicated that the position could overlap but said this would be a short period of time.
They said: “Talks can’t go into the autumn.”
The spokesperson also highlighted how Mr Johnson does not want to be continuing with talks in October.

He wrote on Twitter: “I want to be clear that the Government will not agree to ideas like the one currently giving the EU a new right to retaliate with tariffs if we chose to make laws suiting our interests.
“We could not leave ourselves open to such unforeseeable economic risk.”
Weekly talks are now set to take place throughout July as the intensified process begins.
