About 30 people, some dressed in swimming costumes, walked from Central Park to the MP's home in the city at 2pm on Saturday (13 June).

It followed the recent MPs' expenses revelations during which Mr Jackson promised to repay more than £300 claimed for pool maintenance.

Protest organiser Phil Jeffery, from West Town, Peterborough, said: "The idea has come from the extent of the whole MPs' expenses row. In essence, it was our protest against Stewart Jackson and his claims."

The protesters were greeted at the gates to the property by four police officers.

Today, Mr Jackson, who was "helping local communities" at Dogsthorpe allotments at the time of the protest, said: "Police resources should be used to fight crime, rather than this sort of foolish, juvenile act.

"This was an unnecessary waste of police time."

A spokesperson for Cambridgeshire police added: "The protesters arrived at the property, but they did not enter. They went back to Central Park at about 3pm, and we left the scene at 6.30pm."

"No arrests were made."
