Tens of thousands of security personnel have been deployed in the Pakistani capital Islamabad ahead of an anti-government march, led by the opposition politician Imran Khan.

He is calling on the Prime Minister Nawaz Sharif to resign over allegations of electoral fraud in last year's national election.

The Government has in turn accused Mr Khan of trying to derail democracy.
