LONDON (Reuters) - British Prime Minister Theresa May is clear on the potential dangers of reopening the deal to leave the European Union, her spokesman said on Wednesday, adding that the withdrawal agreement was complete.

Some critics of the deal are pushing May to win more concessions from the EU to try to garner support for the agreement in parliament, which could reject it in a vote on Dec. 11. The EU has said the deal is the best on offer.

May is also meeting lawmakers to try to win their support for the deal, the spokesman said.
