LABOR is being accused of dirty tricks in its win in Lindsay after it distributed a how-to-vote card which looked suspiciously like a Greens one, saying how to vote Greens and preference Labor.

With David Bradbury set to win by a few hundred votes, the dodgy card could have helped Labor over the line, the Liberal Party claims. Labor was leading by 1017 votes last night.

The pamphlet, which Labor said was "ticked off" by the Greens, stated: "Thinking of Voting Green and want to protect our local environment ... give your preference to David Bradbury."

A how-to-vote card then stated: "How to vote Green and preference David Bradbury."

The pamphlet, authorised by Labor Left assistant secretary John Graham, advertised it was "printed on 100 per cent recycled and acid-free paper".

Labor is countering that in Robertson the Liberal Party had big posters with Bob Brown on them encouraging voters not to preference Labor.

The Liberal Party state director Mark Neeham said: "The people of western Sydney have shown they feel betrayed by Labor. David Bradbury knew it and wasn't even game enough to defend his own party.

"He has used desperate tactics, trying to deceive the voters that he was either a Liberal or a Green candidate."

"I think the people of Lindsay will be extremely disappointed that Labor has tried to trick them."

But Labor's general secretary Sam Dastyari responded: "It's disappointing the Liberal Party is saying the people of Western Sydney can't differentiate between political parties. This is just empty excuses for their poor campaign."
