US presidential debate: who won round one?

US President Barack Obama and Republican Mitt Romney have clashed sharply over their economic plans in the first of three televised debates.

Over 90 minutes, the men jousted over their positions on taxes, healthcare reform and the role of government.

The BBC's Katty Kay said Mr Romney "gave a very solid performance", but also asked whether the Obama campaign had made a conscious decision "that they were not going to attack".
