Claims a Labour candidate for mayor broke election rules by handing out brownies while campaigning have prompted a police investigation.
West Yorkshire Police said it was looking into the allegations against Batley and Spen MP Tracy Brabin.
Labour said they were only offered to party members after a day of canvassing – which is not against the rules.
Former actor Ms Brabin is one of seven candidates in the West Yorkshire mayoral election on 6 May.
According to the Electoral Commission, a person is guilty of “treating” if either before, during, or after an election they offer food, drink or entertainment to corruptly influence any voter.
It requires a corrupt intent and does not apply to ordinary hospitality.
The mayoral election was originally meant to take place in May 2020 but was postponed due to the pandemic.
Voters in Leeds, Wakefield, Kirklees, Calderdale and Bradford can all make a selection.
The other candidates standing in the mayoral election are (listed alphabetically):
Waj Ali, Reform UK
