Mum of man killed by drugged driver wants roadside drug testing

Long-serving National MP Nick Smith was named in Parliament yesterday - one of the most severe punishments a Speaker can hand out. Dr Smith has been suspended for one day, which means he's barred from having his vote cast, from sitting on a select committee, from even entering the debating chamber. The situation came to a head after Karen Dow, whose son Matthew was killed by a drugged driver, yelled at the Police Minister Stuart Nash from the public gallery. She had brought a petition calling for roadside drug testing to parliament. When she launched that petition at the end of last year, Mr Nash said a discussion document on the topic had already been approved by Cabinet, and would go for consultation early this year. As Karen waited for her flight out of Wellington, our producer Lydia Batham asked for her take on the day's events.
