Bookies have offered odds of 100-1 on Birmingham MP John Hemming achieving his dream of becoming Liberal Democrat leader.
The MP for Yardley hopes to replace Charles Kennedy at the head of the party despite only becoming an MP last May.
But bookmakers Ladbrokes reckon his chances are slim.
They have veteran MP Sir Menzies Campbell, the party's foreign affairs spokesman, as favourite, on 4-7.
Second favourite is Simon Hughes, the Lib Dem president, on 3-1, and Mark Oaten, the home affairs spokesman, is the third favourite on 4-1.
A Ladbrokes spokesman said: "It is really a three-horse race. We don't think Mr Hemming will have the support among the party in Parliament, or the membership."
Mr Hemming was one of the first candidates to declare his intention of standing, following Mr Kennedy's resignation on Saturday.
Mr Kennedy stood down after confessing he had been receiving treatment for an addiction to alcohol.
The Birmingham MP has admitted he may have difficulty gathering the seven required nominations from Liberal Democrat MPs. There are currently 62 Lib Dems in the Commons.
But he insists support from party members has come in from across the country.
Nominations close at 4pm on January 25.
