From the Crikey grapevine, the latest tips and rumours …

Colsi surprise. The member for Warringah is known for his interesting style choices (Speedos, up-turned collars), but he shocked punters this week with his daring move into the world of fashion with the "Colsi" making an appearance as he sung karaoke during the pollie pedal last week. A Colsi is a blue singlet with a white shirt collar. No one had seen much of the Colsi around before Tony Abbott was seen wearing one, and no one was more shocked at the former PM's attire than the creator of the apparel.
