Labor could win election: Turnbull warns

Malcolm Turnbull has admitted Labor could win a July 2 federal election.

With opinion polls showing voters evenly divided between the coalition and Labor, the prime minister conceded he might lose the nation's top job.

"Shorten is definitely the alternative prime minister, Labor could win the election," he told John Laws on radio 2SM on Friday.

Mr Turnbull revealed he got on well with the opposition leader.

"I don't have scratchy relationship with him at all," he said.

But the policies Mr Shorten was proposing were "absolutely calculated" to stop investment and growth.
