Scottish Nationalist Party's Mhairi Black is set to become the youngest MP since 1667 after unseating Labour's shadow foreign secretary Douglas Alexander during the early hours of Friday. The 20-year-old university student beat the Labour senior figure by more than 6,000 votes in Scotland's Paisley and Renfrewshire South. Black will become the youngest MP since a 13-year-old won a seat at Westminister in 1667. The news came just before Scottish Labour leader Jim Murphy also lost in Renfrewshire East.
