Available for over a year

What sort of diplomat is Sir Tim Barrow - Britain's new ambassador to the EU? We speak to a former colleague. The surgeon David Nott is back in Syria - we have a special report. And we speak to Republican and Democrat congressmen about Obamacare and working together (picture: Tim Barrow being knighted in 2011, credit - Lewis Whyld/PA Wire).
