A Bolton school's efforts to rejuvenate its playing field have been destroyed after travellers moved on to the site, according to local councillors.
Traveller families set up camp on the playing field of St John's Primary School, which had recently been re-seeded in preparation for the new academic year.
Councillor Margaret Rothwell, whose husband and fellow councillor John Rothwell is on the school's board of governors, said the pitches had been ruined just days before the pupils returned after the holidays.
Speaking to Bolton Journal, Councillor Rothwell said: "The school will be starting back in two weeks and the playing field will be in no fit state.
"It has taken a lot of effort to get the field re-seeded and now it is churned up because of the big cars and trailers that have gone right across it."
The council said it had served the travellers with a notice to vacate the land.
A council spokesman said: "The school maintains the playing field, so therefore the council did not undertake any recent re-seeding. However, the council will support the school with regards to restoring the playing field."
