Queensland Liberal MP John McVeigh has resigned from federal parliament, triggering a by-election in the seat of Groom.
Dr McVeigh submitted his resignation on Friday morning due to his wife's ill health.
Prime Minister Scott Morrison described him as a true gentlemen who left parliament with the respect and admiration of his colleagues.
"I commend John for his decision and wish him, Anita and their family all the best, and for Anita to continue on her road to recovery with John by her side," he said.
"Like his father before him, I am sure John will continue to play an active community role on the Darling Downs in the decades ahead."
Dr McVeigh was first elected in 2016 after stints in state parliament and local council.
He served in federal cabinet for eight months as the minister for regional development, territories and local government.
The impending by-election is unlikely to trouble the Morrison government.
The coalition holds the Toowoomba-based seat by an extremely comfortable 20.5 per cent margin.
Dr McVeigh received a favourable 5.2 per cent swing in 2019 and retained the seat with 70.5 per cent of the two-party vote.
The by-election will be the second for the year after an earlier contest in the southern NSW seat of Eden-Monaro.
Speaker Tony Smith is considering possible by-election dates.
