Lady Smith unveiled John Smith Avenue on the Clem Attlee Estate in Fulham, west London, as part of celebrations to mark the completion of the first phase of a redevelopment on the estate.
She was joined by the widow of the former Labour mayor of Hammersmith, Len Freeman, who died in 1995 and has also had a street named in his memory.
Opened in 1957 by the leader of Labour's post-war government, the estate has been rebuilt in a pounds 10m scheme by Notting Hill House Trust in partnership with Wimpey Homes and Hammer- smith and Fulham Council.
Touring the estate yesterday, Lady Smith said: "I'm very excited and very impressed by this project. The estate looks like a very pleasant environment in which to live. The reason I agreed to come along today was because this project seems to be making a real difference to people's lives."
Once a series of high-rise blocks, the estate now sports a mix of low- rise houses and flats.
Neil Newton, managing director of the London Borough of Hammersmith and Fulham, said: "If people are happy and proud of the community in which they live they will take good care of it."Reuse content
