The arrival of travellers in East Brighton Park has prompted the Conservative MP for Brighton Kemptown to write to Sussex Police and Brighton and Hove City Council.
Simon Kirby said that he had urged police and council chiefs to move on the group.
Mr Kirby’s office said that he wrote after receiving representations from constituents who have seen the latest unauthorised encampment in the park.
Mr Kirby said: “Once again we have an unauthorised traveller encampment in East Brighton Park.
“I need to reassure my constituents by advising them when the travellers are to be moved on and I have asked the council and the police to advise me accordingly.”
