Scottish Referendum: Why has pound fallen ahead of vote?

The pound has fallen to its lowest level in 10 months amid uncertainty about Scotland's future within the UK.

The currency fell 1% against the dollar in early trading on Monday, and also fell almost 1% against the euro.

It came after a YouGov poll suggested supporters of an independent Scotland had taken a narrow lead in the referendum debate for the first time.

The BBC's Simon Jack explains why the pound is being affected ahead of the vote on 18 September.
