Wimbledon’s Lib Dem MP, Paul Kohler, and Labour MP Fleur Anderson are two opposing the plans.
They say the proposal for the former Wimbledon Park golf course represents an “industrial scale” development.
Merton Council approved the plans, but the proposal was referred to the GLA after Wandsworth Council rejected the scheme last November.
A decision which is due at the end of the month.
The All England Club, which is behind the world famous Wimbledon fortnight, says the plan has been designed with two core objectives in mind:
“The transformation of the former Wimbledon Park Golf Course has been designed with two core objectives in mind:
– to maintain The Championships at the pinnacle of sport, by bringing Qualifying to SW19.
– to provide year-round substantial public benefit to those who live locally to the Grounds.
These proposals have been developed with the highest level of appreciation for the history and heritage of the existing landscape.
The proposals will result in an additional 38 grass courts, as well as a new Show Court, allowing the AELTC to bring the Wimbledon Qualifying event on-site for the first time.
These will mean that Wimbledon can remain as the world’s premier tennis tournament, with all the associated substantial social and economic benefits that the event brings, locally, for London and nationally.”
