Specifically, Tory Senator Marjorie LeBreton, who was observing the convention from a balcony when:
...some toughs from the Michael Ignatieff campaign decided to roust her from her last-row seat. They had decided the seats were reserved for their Ignatieff camp buddies. First, they told her to leave. Then they called security. When none of that worked on the tough senior politician, they just got rude.The Ignatieff campaigners stood in front of LeBreton, staring at her. They eventually forced her to move.
Shame, Iggy, shame! Let's not lose this one ugly, shall we?
