Brisbane LNP councillor Matthew Bourke has announced his resignation from the council ahead of the March 2020 elections, saying he wishes to "take stock" and seek new challenges.

The Jamboree ward councillor and chairman of the powerful city planning committee was first elected to council in 2008 under former LNP mayor Campbell Newman.

Since then he has held differing roles in the council's civic cabinet under former lord mayor Graham Quirk and lord mayor Adrian Schrinner.

Cr Bourke told News Corp on Tuesday night he was resigning, after the LNP had denied any questions about the future of his council role.
