This week on The House, Evan Solomon asks Foreign Affairs Minister John Baird in an exclusive interview why Canada suddenly cut off diplomatic relations with Iran. Are new security threats on the rise?

Then to get a bigger picture of what's happening behind the scenes, we speak with Ray Boisvert, a former Assistant Director of Intelligence at the Canadian Security Intelligence Service.

And now that Quebec has elected a new government, we ask Bernard Drainville, a Parti Quebecois MNA, whether PQ Leader Pauline Marois will put aside her sovereigntist agenda. Is the prospect of a referendum still on the table?

And we welcome back CBC's resident blogger Kady O'Malley, who's here to answer all your good questions. This week: Was it correct to automatically assume the Parti Quebecois would form Quebec's new government? What about the possibility of a coalition?

And to wrap up this week's show we chat with Rob Russo of The Canadian Press and  Radio-Canada's Emmanuelle Latraverse about what to expect as Parliament gears up for the fall sitting.
