The Liberal National Party will host a celebration of International Women's Day at an exclusive Brisbane club that only allows men to be members.

The lunch will be held at the Tattersall's Club from 11.45am on Friday, two days before International Women's Day on March 8.

An LNP spokesman said the lunch had been organised by party organisation LNP Women.

"Nearly half of the LNP's 14,000 members are women and this event aims to discuss and promote the involvement of more women in politics at all levels," he said.
