Welcome to On Topic with the Weekend Briefing, a special series where Jamila Rizvi talks to some of her favourite guests - old and new - about a single, fascinating subject.

Over the next two months, you’ll hear from singers, writers, models, actors and change makers on topics as diverse as power and influence, mindset and money, bodies and brains.

Today you’ll hear from Sean Kelly, on politics. Sean is a columnist for the Nine papers and a regular contributor to The Monthly. He was a political adviser to Kevin Rudd and Julia Gillard.

In this chat with Jamila Rizvi, Sean explains politics as a performance, the fracturing of the two party system, the entrenchment of attitudes and opinions - and what it means if Australians treat politics as a game.
