Malcolm Turnbull now no longer holds a majority in parliament
Mr. Joyce, leader of Mr. Turnbull's coalition partner, the National Party, is running in a by-election to win back his seat. Mr Alexander has indicated he will do the same.
Earlier in the week, Mr. Turnbull unveiled plans to make federal politicians clearly declare their citizenship status to avoid a similar crisis in the future.

Current politicians will have 21 days to make the declaration, while future members of parliament will be required to make the declaration when they are elected.
