Labor pledges to block tax cuts

Labor will block the coalition's proposed corporate tax cuts in the Senate if the government is returned to power on July 2.

Opposition Leader Bill Shorten was asked at the leaders' debate whether Labor would respect a coalition government's mandate on the 10-year tax cut plan outlined in the May budget.

"I have to say that when it comes to corporate tax cuts Labor doesn't think they're the right idea for this nation - full stop," Mr Shorten said on Sunday.
