Queensland voters back the LNP over Labor and talk of leadership tension was "rumour and speculation", the party's deputy leader said on Sunday.

However Everton MP and former rugby league referee Tim Mander appears to be winning support of 17 LNP MPs from Mr Springborg, who had 12 votes on Sunday night. Tim Nicholls also has 12 votes, a source said.

Surfer's Paradise MP John Paul Langbroek, one of the LNP's senior MPs, said consistent polls showed voters wanted the LNP.

"The important thing is we are leading two-party preferred," Mr Langbroek said.
