LONDON (Reuters) - British Prime Minister Theresa May said she is seeking to renegotiate the Brexit divorce deal agreed with the European Union to secure “significant” changes although this is likely to face strong resistance from the bloc.

“What I am talking about is not a further exchange of letters but a significant and legally binding change to the withdrawal agreement,” May told parliament on Tuesday.

“Negotiating such a change will not be easy. It will involve reopening the withdrawal agreement, a move for which I know there is limited appetite among our European partners.”
