David Cameron's hopes of becoming prime minister were on a knife edge on Friday morning, as results suggested the most unpredictable general election in years would produce a hung parliament.
The Conservative leader insisted that Labour had “lost its mandate to govern” as the Tories made big gains and easily overtook Labour as the largest party at Westminster. But he faced an agonising wait before learning whether he could assemble enough seats to command a Commons majority.
Amid signs that the election would produce no clear result, Gordon Brown was engaged in frantic talks on whether he could stitch together a coalition of his Labour party with Nick Clegg's Liberal Democrats to keep the Tories out of power.
