Prime Minister Tony Abbott will join the Griffith byelection campaign this weekend, joining Liberal National Party candidate Bill Glasson as the Coalition attempts to increase its parliamentary majority by one.

An LNP spokesman confirmed Mr Abbott would attend Dr Glasson’s campaign launch, which will be held at Easts Leagues Club at Coorparoo on Saturday morning.

It will be the first visit by Mr Abbott during the byelection campaign and comes more than a week after Opposition Leader Bill Shorten concluded four days on the hustings with Labor candidate Terri Butler.

Mr Abbott has been conspicuously absent from the LNP’s how-to-vote cards and other byelection paraphernalia, an absence that was latched on to by Mr Shorten and Ms Butler at Labor’s campaign launch last week.

The Glasson campaign countered that criticism by saying it was running on local issues.

The Griffith byelection will be the first electoral test for Mr Abbott’s fledgling government.

Dr Glasson won the Griffith primary vote in the 2013 general election, winning 42.22 per cent compared to then-prime minister Kevin Rudd’s 40.36 per cent.

However, Greens preferences saw Dr Glasson defeated by Mr Rudd  53.01 to 46.99 per cent.

Communications Minister Malcolm Turnbull, a popular Coalition figure among inner-city Griffith’s swinging voters, is expected to join the campaign early next week.
