Labor's Mark McGowan gave away free mints, Liberal candidate Lily Chen handed out bottles of plonk and Liberal leader Colin Barnett is often accused of giving away WA's economy.

But One Nation leader Pauline Hanson looks set to trump them all with an event dubbed 'Pots and Pizzas with Pauline' at the Paddington Ale House on Thursday night, inexplicably right in the heart of gentrified Mt Hawthorn.

The event - confirmed to WAtoday by the pub's management - will see Ms Hanson shout the first hundred drinks and lay on a free feed to those who come along to hear her speak in the closing days of WA's tight state election campaign.

Ms Hanson's far-right party is tipped to wrest control of the balance of power in the upper house, following a controversial preference deal with the Liberals.
