PM prepares to chair meeting amid latest Brexit row
Senior MPs that back Brexit have demanded that Theresa May drops a proposal for a customs partnership with the European Union once it leaves the bloc
A customs partnership is one of two proposed options that May's government has proposed on customs, and means Britain would continue to collect EU tariffs for goods which are headed for member states.
But a 30-page document passed to the BBC said the lawmakers customs partnership option would make it "impossible" to strike meaningful trade deals.
The BBC said that sources close May said she was "relaxed" about the ultimatum and was confident about reaching an agreement with senior ministers over a replacement for the current customs union.
