Cabinet Office minister Michael Gove is heading to Brussels at the start of a week of talks about the UK’s future relationship with the European Union.
Mr Gove will meet European Commission Vice President Maros Sefcovic to discuss implementation of the Brexit divorce deal.

An EU spokesman said their chief negotiator Michel Barnier was neither optimistic nor pessimistic but determined to reach a deal.
The Brexit transition period, in which the UK has kept to EU trading rules, ends on 31 December. The UK and EU are yet to agree a deal
