A supermarket is embroiled in a dispute with its neighbours days after opening.
Lidl, who have developed a former service station site on Avondale Street, Standish, has been accused of thumbing their nose over planning restrictions.
A councillor whose home backs onto their site is now demanding enforcement action after the company erected an advertising hoarding fronting Preston Road plus "unauthorised" floodlights over the car park.
Indepedent Conservative leader on Wigan Council Coun Gareth Fairhurst, who lives in nearby James Place, said: "A planning application for an advertising bill board and that was refused. It looks to some of us that they are laughing at the council and thumbing their nose at the planning laws."

Metro Service Director Development Steve Normington said: "We received complaints from local residents regarding the car park lighting and the billboard lighting and these have resulted in formal discussions occurring with Lidl to resolve the matter.
"The council have written to Lidl to inform them that the billboard requires consent and advising them to apply by April 6 or remove it. If they continue to display it without consent, the council will look upon it as a breach of planning and consider legal action."
A spokesman for Lidl confirmed they were liaising with the Metro about the car park lighting, while he pledged the hoarding would also be removed shortly.
He said: "Although no condition was attached to the approved planning permission, details of the car park lighting have been reviewed by council officers, who have requested further information.
"The non-illuminated hoarding on the Preston Road boundary was initially used as a construction information board to let potential customers know the opening date which was postponed due to bad weather."
