Outgoing Green MP Sue Kedgley has called for a change to the "trench warfare" nature of Parliament, saying the public finds politicians' behaviour off-putting and childish.
Ms Kedgley, who will step down at this year's election, used her valedictory speech today to question the "polarised and confrontational" business tactics of MPs.
"Much of the time it's trench warfare in here," she told Parliament.
"The aim is to do battle, to defeat the enemy on the other side, not to debate or to listen. The heavy hitters, the point scorers and the alpha males lead the charge, and hurl abuse and insults at the other side.
"Question time, which ought to be a showcase of our democracy, routinely degenerates into a pointless slanging match."
