People have tried to bet on Boris Johnson setting his hair on fire with the Olympic torch, the colour of the tie to be worn by the Chancellor and whether Cherie Blair would give birth to an alien.
Susana Mendonca spoke to bookmakers about political betting and more mainstream punts including the current odds for David Cameron, Ed Miliband and Nick Clegg at the next election.
She also looked back at how John Major was once 33-1 to take over as his party leader, and Lord Sutch's odds of entering Downing Street as PM.
