After a meeting in Brussels, European Council President Donald Tusk said Ms May would have to finalise her deal by December 4 when she is expected to meet other key EU officials. 

The EU has refused to discuss trade and transition arrangements until sufficient progress is made on issues of Northern Ireland, citizens’ rights and the "so-called" divorce bill - with Mr Tusk demanding greater clarity from the UK before moving forward.
