Australian Prime Minister Malcolm Turnbull has confirmed he intends to call an election for 2 July.
On Monday Australia's upper house, the Senate, rejected a piece of government legislation for a second time.
This provided Mr Turnbull with a trigger for a so-called double dissolution election.
Mr Turnbull said at a press conference on Tuesday that he intended to ask the governor general to dissolve parliament after the budget on 3 May.
He said calling the double dissolution was about "giving the people their say".
Australia has a two-party system, as illustrated by the two-party-preferred vote, with two dominant political groupings in the Australian political system, the Australian Labor Party, and the Liberal/National Coalition. Prime Minister Malcolm Turnbull is the leader of the Liberal Party.
