Malcolm Roberts, a spry, climate-change denying, Indian-born coal-miner's son who was elected to Parliament with a boutique constituency of just 77 personal votes, has been ejected from the Senate.

According to the High Court, Roberts was a British citizen when he was elected, which is especially galling when you consider that Roberts' bio on the One Nation website calls out "the foreign control wrecking our country".

To be fair, Mal did take steps to renounce his British citizenship.

It's just that he took those steps both after he was elected, and via email to a non-existent address at the British Embassy, sent with the rather damning subject line: "Am I still a British citizen?".
