Horsham MP Francis Maude said: “Our offer is generous and fair to public sector workers and other taxpayers. Many low and middle income workers will actually receive a larger pension income at retirement.

Chief Superintendent Paul Morrison who is leading the police operation said: "Sussex Police will, as always, facilitate what is anticipated to be a peaceful day of protest and will protect the rights and freedom of others to go about their lawful business without fear of threats, intimidation or unreasonable disruption.

"In Brighton there is expected to be a large march and protest, with demonstrations also planned for Worthing, Horsham and Hastings.

"We have been engaging with the organisers, who have been very co-operative and have informed us of their planned routes and activities. This has helped us plan for the events, although exact numbers of protesters are unknown."

Gatwick

UK Border Agency staff, who look after passport control at all airports, are on strike.

Scott Stanley, Gatwick Airport’s Chief Operating Officer said: “The strike action by UK Border Agency staff will regrettably present frustrations for arriving passengers required to pass through border agency checks today.
