Prime Minister Theresa May was fighting to hold on to her job on Friday as British voters dealt her a punishing blow, denying her the stronger mandate she had sought to conduct Brexit talks and instead weakening her party's grip on power.

With no clear winner emerging from Thursday's parliamentary election, a wounded May signaled she would fight on, despite losing her majority in the House of Commons. Her Labour rival Jeremy Corbyn said she should step down.

With 643 out of 650 seats declared, the Conservatives had won 313 seats and were therefore no longer able to reach the 326 mark they would need to command a parliamentary majority. Labour had won 260 seats.
