Britain's Prime Minister Theresa May says it would not be in the national interest to hold another general election just as she is negotiating the terms of Britain's exit from the European Union.

May is under intense criticism over her approach to leaving the European Union, fuelling speculation she could be ousted by her own party, or that her minority Conservative government could collapse

She said Britain would reach a Brexit deal despite a current impasse in talks with Brussels. If Britain and the European Union agree on a deal, it must be approved by individual nations before Britain leaves.
