Bulgaria, which holds the presidency of the EU on Thursday warned of poor progress in Brexit talks and told Britain it was still not too late to abandon its plan to quit the bloc.

Boyko Borisov, the Bulgarian Prime Minister said he had so far seen nothing in the talks on Britain’s exit in March 2019 to give him hope for a good outcome.

The comments will come as a blow to British Prime Minister Theresa May as her senior ministers embark on a flurry of speeches to outline Britain’s ambitions for Brexit.

The EU wants to finish talks on the post-Brexit transition period by the end of March so negotiations on future ties with Britain can start, but has warned that deadline could be pushed back if there is no progress from London.

May’s government is battling deep divisions between Brexit moderates and hardliners as it prepares for crucial talks with Brussels over the future relationship, which start in April.
