An anonymous Twitter troll is targeting the state government by airing unsubstantiated speculation about Labor organisations, politicians and staff.

'WA Politics Tips Line' first tweeted on Saturday about the financial affairs of an unnamed union and has since published rumours about a City of Perth councillor and implied employees have quit a minister's office over a Labor staffer's alleged conflict of interest.

The account has also implied there is a "former state party leader planning a comeback to his old job".

The tweets do not name those at the centre of the speculation but are instead framed as questions.
