The revamp will see the stadium reconfigured as a rectangle instead of its former Olympic specification oval, with the focus on football, rugby league and rugby union.

The capacity will also be cut from its current cavernous 85,500 to just 70,500, with the option of a crowd of up to 90,000 for concerts.

A new semi-translucent roof will also be installed under the proposed plans which will allow light through while still providing shade and shelter for fans all round the stadium.

The design will see most of both ends of the stadium demolished and rebuilt with major upgrades elsewhere in the building for toilets, corporate hospitality and food and drink stands.

Seating in the mid to lower sections on the sides will also be upgraded and brought in at a steeper rake to improve visibility, and changing rooms will be made unisex, while state of the art giant screens will be also installed.
