Glasgow 2014: City set for Commonwealth Games opening ceremony

The Queen will formally open the 20th Commonwealth Games in Glasgow later in front of a 40,000 crowd at Celtic Park.

Organisers say a global TV audience of up to a billion people is expected to watch the event from 21:00 BST.

Thousands of cast members and athletes will take part in the opening ceremony - but the content has been kept tightly under wraps.

Lorna Gordon reports.
