The Chief Constable of Gloucestershire will join thousands of officers at a protest march in London today.
Tony Melville, who is resigning over budget cuts, has taken a day off to take part.
The march, similar to this one in 2008, is in protest at cuts to force budgets and proposed changes in terms and conditions. Off-duty officers from across the region, inlcuding two hundred from Dorset, will also be there.
