Mayor of Tower Hamlets Lutfur Rahman said: “We are delighted to be a part of BT London Live and as one of the host boroughs the excitement to the build up to the Games is palpable.

“BT London Live will enable Londoners and visitors to get closer to the Games and what better way to watch the events than outdoors on a massive screen in an iconic location like Victoria Park.”
