David Seymour: ACT leader defends attempt to drive Land Rover up Parliament's steps - Heather du Plessis-Allan Drive

David Seymour is playing down criticism after he drove a 77-year-old Land Rover up the front steps of Parliament. 

Parliamentary security stopped the ACT leader before he got further than a few stairs.

Seymour says it was just a bit of fun and he was doing it for charity - to raise money for children's heart disease.

"I think if the people from 1948 were around, they'd be astonished that I got to talk on the wireless for doing this rather mundane act."
