A Double Dissolution
The PM has just left The Lodge to call on the Governor General to dissove both houses of Parliament and call a double dissolution election for 2nd July.
A double dissolution means that the whole senate is now up for grabs instead of only half. It also means you only need half the number of votes to get a quota.
It also means there will be a loooong campaign of 8 weeks. According to the opinion polls on a two party preferred vote the two major parties are running neck and neck at 50% each.
