Vladimir Putin certainly knows how the West views his actions in Ukraine. Sanctions have been in place against Russia for months. There is talk of toughening them. At the G20 meeting in Australia he was rebuked by Angela Merkel, Stephen Harper and other leaders, before flying home early. But are sanctions having any real effect on the Russian president? Are they likely to force him to change course in Ukraine? We hear from a top Moscow economist Natalia Orlova, a Putin loyalist in Vladivostok, veteran European diplomat Sir Robert Cooper and Fyodor Lukyanov, editor of Russia in Global Affairs and a close Putin-watcher.

Hong Kong's government is preparing to clear the streets after weeks of protest. The demonstrators want direct talks with Beijing over who gets on the ballot for the 2017 Hong Kong election.

The sudden rise of Islamic State in June shocked the world. It now controls a swathe of the desert in Syria and Iraq and has declared a caliphate. Iraq’s second city, Mosul, has fallen to the militants and they are menacing the capital, Baghdad. Western powers and their Gulf Arab allies have responded with war planes and bombs. The American general in charge of the campaign says it is buying time for the Iraqi Army to regroup and counter attack. But what would a long-term plan to defeat Islamic State look like? The Inquiry’s panel of experts have some thought-provoking ideas.
