Bookmaker William Hill says it's seeing a flurry of bets on a white Easter, and is now offering the shortest price in the history of weather betting.
The odds on snow falling in London on Easter Sunday are now just 2/1, down from 16/1 three weeks ago. It's now offering 25/1 that snow will fall in London on the day of the boat race.
The bookmaker has closed betting on a freezing temperature being recorded on the mainland on Easter Sunday, saying it's become "a virtual certainty"
