Royal Marines will be stationed in inflatable boats along the length of the Boat Race course on Sunday to ensure the event is not disrupted by another protester, organisers said today.

Oldfield, who claimed to be protesting against elitism, was released from prison in December having served seven weeks of a six-month sentence after being found guilty of causing a public nuisance.
