Following the 2005 general election, Howard promoted him to Shadow Chancellor of the Exchequer at the young age of 33. Howard had initially offered the post to William Hague, who turned it down. Press reports suggest that the second choice for the post was David Cameron, who also rejected the job, preferring to take on a major public service portfolio (he was made Shadow Secretary of State for Education). Thus, Howard seems to have turned to Osborne as his third choice for the role. His promotion prompted speculation he would run for the leadership of the Conservative Party when Howard stepped down, but he ruled himself out within a week. Osborne served as campaign manager for David Cameron's leadership campaign, and kept the Shadow Chancellor's post when Cameron became leader later that year.
