Coalition members have criticised ALP ads which draw attention to the Prime Minister corporate past as the main reason for the coalitions new plans to cut corporate tax rate.

LNP backbencher Scott Buchholz said no one cares how much Malcolm Turnbull is worth, although federal opposition members are saying the ads are fair game.

The ALP ads said the Prime Ministers financial interest register show he directly owns shares in 32 companies worth over 50 million dollars.
