There’s more chance of PUP merging with the Labor or Liberal parties than with KAP, Clive Palmer says.

Clive Palmer has stomped on persistent speculation his political party could merge with Bob Katter’s.

Palmer United Party’s Queensland leader Alex Douglas last month said the potential tie-up with Katter’s Australian Party (KAP) would “most likely” occur under the Palmer brand, a comment the wealthy MP swiftly smacked down, saying “news to me” in a text to Fairfax Media.

At the same time, KAP MP Robbie Katter told the ABC that any merger between the parties would be “nothing to be sneezed at”.

But Mr Palmer told AAP this week, while on the hustings in Perth ahead of the reprised West Australian Senate election, that the parties had little in common.

“The true story about that was Bob’s vote was right down, and he’s always trying to get notoriety in the press so he always leaks this every three months,” he said.

“The Katter Party is an extreme right party and our party is a more centre party.

“And we disagree on certain things, such as guns … a whole lot of things Bob’s in favour of.”

Mr Palmer said the leaders might like each other personally, but a political party had to share the same beliefs.

“There’s more chance of us merging with the Labor or Liberal parties than with Bob.”

KAP was being sought for comment.
