Defence Secretary Geoff Hoon has been pelted with eggs by demonstrators during a visit to East Yorkshire.
Mr Hoon arrived at the Toll Gavel Methodist Church in Beverley on a visit to support the Labour Party's parliamentary candidate George McManus.
Pro-hunt demonstrators had gathered outside the church to protest about the pending introduction of laws banning hunting with dogs.
Mr Hoon said he was "extremely disappointed" by the action.
Humberside Police force said some of its officers were pushed to the ground.
A spokesman said the actions of pro-hunting supporters was "unacceptable".
As long as the eggs dented his delusional sense of his own self-importance, mission accomplished. Good on Humberside's finest. Good to see the Nelson touch remains alive and well among the men in blue suits.
