|Shadow foreign secretary - William Hague
Mr Hague was the youngest leader since William Pitt when he took over the party in 1997 at the tender age of 36.
But the Tories gained only one seat overall at the 2001 election and Mr Hague promptly resigned.
Since then, he has enjoyed a lucrative business career and built up credit with his back bench speeches.
Mr Hague entered Parliament in 1989 having been special adviser to Chancellor Sir Geoffrey Howe. He was soon promoted to be a social security minister and in 1995 entered the Cabinet as Wales secretary.
