Royal Marines will be positioned along the bank of the River Thames between Putney and Chiswick for this year's Boat Race. It comes after protestor, Trenton Oldfield was jailed for swimming across the path of rowers during last year's race.
Oldfield was released from prison in December 2012 after serving seven weeks of a six month sentence for causing a public nuisance.
The Metropolitan Police recently contacted him to see if he was planning to protest at the 2013 event. Oldfield wrote back saying "I'll probably have a walk in the Cotswolds instead."
