London Mayor Boris Johnson has once again won a seat in parliament, this time representing voters in the Uxbridge and Ruislip South district, as Conservative Party candidates did much better than expected in Britain’s election. The shaggy-haired mayor, seen as a possible future Conservative Party leader, had previously represented Henley. “The people of Britain, after a long and exhausting campaign, have finally spoken,” he said early Friday. “They have decisively rejected any attempt to take this country back to the 1970s. They want us to go forward with the sensible, moderate policies that have led to a sustained economic recovery.” Johnson will do both jobs until voters choose a new London mayor in 2016.
