Coalition and Labor in poll deadlock

As Prime Minister Malcolm Turnbull prepares to head to Canberra to ask for a double-dissolution election, a new opinion poll has Labor and the coalition neck and neck.

The first post-budget Galaxy poll commissioned by The Sunday Telegraph indicates the two major parties are locked at 50-50 on a two party preferred basis.

The coalition still leads Labor on primary votes, 42 to 36 per cent.
