The Liberal candidate for Mirrabooka has apologised for handing out bottles of wine while doorknocking, saying it was an “error of judgment”.

Lily Chen, a City of Perth councillor and a lawyer, gave out bottles with her name and picture on the label.

A resident claimed her 11-year-old autistic son was given a bag containing a bottle of wine and brochures while she was in the backyard.

Ms Chen denied giving alcohol to a child but when asked if she had left wine on the doorstep, she said any further comment would come from a media adviser.

A Liberal Party spokesman said: “In keeping with Chinese traditions and in recognition of Chinese New Year, Lily Chen was, for a short period of time, distributing bottles of wine during doorknocking in the Mirrabooka electorate.

“Lily now realises this was not appropriate and apologises for her error of judgment. She apologises unreservedly for any offence that has been caused.”

Ms Chen suggested a Labor supporter was trying to cause trouble.

“I never gave any wine to a person under 18,” she said.

“I wouldn’t have given alcohol to a young person, unless mistakenly someone picked it up ... from my memory nothing happened.”

Premier Colin Barnett said Ms Chen’s decision to hand out wine bottles was unusual and “not the way to go”

"Lily is a fantastic person and highly qualified, Chinese obviously, an expert on Russian language and history and also qualified as a lawyer and she would be a fantastic person to see in Parliament,” he said.

"Look, (it was) not the right thing to do, but we like to be inclusive and respect different cultures and traditions.

"Maybe it’s something that’s not the traditional Australian conservative way but maybe it is part of Chinese culture, I don't know.”
