LONDON (Reuters) - Prime Minister Theresa May is still working on obtaining assurances from the European Union which British lawmakers have said they need before they could vote for her Brexit deal, her spokesman said on Monday.

May pulled a parliamentary vote on her Brexit deal in December after admitting it would be rejected, and her spokesman said she was still working on getting the necessary assurances from Europe’s leaders.
