Theresa May and other key Cabinet members are understood to be planning to discuss raising Britain's 'divorce bill' offer to break the Brexit negotiation deadlock.
Donald Tusk, the president of the European Council, has told Britain that EU negotiators will not move on to the crucial trade stage of the Brexit talks unless significant progress is made on the financial settlement issue by the start of December.
In response, the Cabinet Exit and Trade sub-committee is to gather in Downing Street, reportedly to discuss a revised, improved financial offer.
Reports last week suggested the Prime Minister was due to add a further £20bn in payments to the EU to settle the bill.
This would increase the value of the UK's offer to around £38 billion - although this is still short of 60 billion euros (£53 billion) Brussels is reportedly seeking.
Downing Street dismissed the reports as speculation, and representatives for the Prime Minister refused to discuss the agenda for Monday’s meeting.
Despite this, ministers remain positive, with Philip Hammond telling Andrew Marr on the BBC the team was on the brink of taking a crucial step forward in the talks.
