London: British Prime Minister Theresa May will seek "changes" to the withdrawal agreement she negotiated with EU leaders last month, her spokesman said on Tuesday even though Brussels has insisted it will not re-open the deal.

"We have to have a deal which can carry the support of parliament and that's going to require some changes to the withdrawal agreement," the spokesman said ahead of a series of parliamentary votes on Britain's Brexit strategy.
