The Met said 21 people were recalled to prison, and 11 firearms and more than 40 knives seized in a bid to target those who 'pose the greatest risk' of causing trouble.

Organisers say 7,000 officers and staff will be on site today and tomorrow with live facial recognition cameras and screening arches to detect weapons at the busiest entry points.

In an update at 8pm on Sunday, the force said dozens of arrests were made on the opening day, including 15 for assaults on police.
