Police were forced to break up a late-night election count fracas in St Helen's.
A row broke out as Liberal Democrats in Labour-controlled St Helen's suffered a series of setbacks, leading to disappointment for the party's leader on the council, Brian Spencer who lost his seat.
According to witnesses at St Helen's Town Hall there was a confrontation between Mr Spencer and Labour candidate Mark Johnson, who fell across a table and landed on his mother.
It is understood police officers intervened, but no arrests were made.
Lib Dem councillor Michael Haw said Mr Spencer, the council's ex-opposition leader, was upset at losing his seat.
