It's another challenging week for Head of Deliverance, Ian Fletcher, and his team. Roman remains of potentially national significance have been discovered on the site of the aquatics centre, forcing them to contemplate radical last-minute modifications to the design of the building.

Head of Infrastructure Graham Hitchins is grappling with the sensitive issue of civil aviation flight paths during the period of the games, and Head of Sustainability Kay Hope is faced with recording her own video blog at the Olympic site itself.
