A City of Perth councillor hoping to leap into state politics is under fire for handing out free bottles of wine while doorknocking in her nominated seat of Mirrabooka.

Lily Chen, a councillor at the embattled City of Perth since 2011, was accused by a local resident of leaving a bag with a bottle of wine labelled with her picture, contact details and campaign slogan with the woman's 11-year-old autistic son.

Lily Chen's self-branded wine she was giving residents in Mirrabooka, the seat she hopes to win off Labor at the state election.

The gift to potential voters in the electorate she is running in was passed off by the Liberal Party as a celebration of Chinese culture.

Ms Chen denied giving alcohol to a child and told The West Australian any further comment on the matter would be made by a Liberal Party media adviser... who confirmed she had given the bottle to the boy.
