More or Less: Behind the Stats - WS More or Less: Who Won the US Presidential Debate?

Polling on the first TV debate between Hillary Clinton and Donald Trump appears to be divided over who won it. But not all polls are equal. If the people being polled aren?t representative of the population at large, then their responses may not tell you anything useful. And when internet polls can be hijacked by online activists, they can throw up some pretty strange results.

This week Donald Trump claimed that there are some inner city areas in the US which are suffering from the worst crime rates ever. They are so dangerous, he says, that Afghanistan is safer than many of these areas. But could this be true?

Start the Week - Political Drama: Robert Harris and Margaret Hodge

On Start the Week Andrew Marr talks to the MP Margaret Hodge who challenged multinational companies to explain their tax affairs and shone a light on the billions wasted by government every year. The former Chair of the Public Accounts Committee argues that it's time Ministers and Civil Servants learnt from their mistakes. Sir John Armitt masterminded the successful delivery of the 2012 London Olympics and explains why big projects are notorious for budget overspends. MPs will have to decide soon on a multi-billion pound proposal to renovate the Palace of Westminster which would involve them moving out for several years: the political journalist Philip Webster reflects on working in the House of Commons for four decades and how the building influences the business of politics. The best-selling novels of Robert Harris reveal the machinations behind the closed doors of those in power, or seeking it - from Ancient Rome to New Labour. His latest book centres on the intrigue in the corridors of the world's smallest state, the Vatican, as they vote for the next Pope.

More or Less: Behind the Stats - WS More or Less: Drug deaths in the Philippines

Over the last two months the Government in the Philippines has been encouraging the police to clampdown on the illegal drug trade.
