British Prime Minister Boris Johnson said the day ``marks a new beginning in our country's history and a new relationship with the EU as their biggest ally.''

All parties worry that they could be hurt by voters' Brexit fatigue.

British lawmakers voted on Thursday to seek a delay in Britain's exit from the European Union, setting the stage for Theresa May to renew efforts to get her divorce deal approved by parliament next week.

British lawmakers on Wednesday rejected leaving the European Union without a deal, in a non-binding vote which will increase pressure on Prime Minister Theresa May to rule out a 'no-deal' exit.

Britain's opposition Labour Party will support a second referendum on Brexit if parliament rejects the party's alternative plan for leaving the bloc, its Brexit spokesman said Monday.

The 432-202 vote in the House of Commons was widely expected but still devastating for May, whose fragile leadership is now under siege.
