Europe's stock markets slide in the wake of falls in Asia and the US. We get analysis from Chris Low from FTN Financial, and our regular economic commentator, Roger Bootle of Capital Economics. And we hear how automated computerised trading has changed the nature of stock markets around the world. Also in the programme, the BBC's Mariko Oi tells us what deals are being struck at the Singapore Air Show. Plus, a century after some women in the UK won the right to vote, we hear how the struggle for gender equality is still a work in progress.
