Delhi's Commonwealth Games legacy

21 July 2014 Last updated at 06:42 BST

The Commonwealth Games in Delhi four years ago provided the city with world class facilities.

The athletics event cost $2.5bn (£1.5bn) and brought investment and renovation to the city.

But many athletes complain that soon after the games, facilities were closed.

With the Commonwealth Games about to kick off in the Scottish City of Glasgow, there is a lot of talk about whether the costs really do bring enough benefits.

Four years on, the BBC's Shilpa Kannan reports from Delhi on whether the legacy was worth it.
