The LNP is growing increasingly confident Campbell Newman will hold his seat of Ashgrove.

While a recent poll has former Labor MP and minister Kate Jones as the preferred candidate, it also indicated that the voter perception was Mr Newman would win.

The government has spent more than $100 million shoring up the seat for the LNP, with Mr Newman promising an additional $18 million worth of commitments as part of the "Ashgrove Plan" on the first day of the LNP policy releases.

The high number of public servants who live within the electorate had given the LNP pause that it would lose the seat - and thereby it's parliamentary leader - but sources say the party is growing more confident "every day" that Mr Newman will prevail.

"They have a choice between having the Premier and an opposition backbencher as their local member, that is the choice," one party source told Fairfax Media.
