The authority has been awarded the legal powers to acquire the space and redevelop it into housing and a pontoon.
The Twickenham Riverside Trust was granted a 125-year lease in 2014.
Lord Nicholas True, the council’s Conservative leader at that time granted the Trust the lease “ in perpetuity for the people, so that never again can any other council come forward with a plan to sell the Gardens off to a developer”.
But the current Lib Dem run council launched a Compulsory Purchase Order in 2021 to allow development to take place.
Current Lib Dem leader, Gareth Roberts has tweeted;
“Following a long, drawn-out process the Planning Inspector has found in the council’s favour and has awarded us legal powers to acquire Diamond Jubilee Gardens so we can Get Twickenham Riverside Done.”
