Streatham will remain united under new proposals to bring it together with Clapham to form a single parliamentary constituency.

The Boundary Commission has revised proposed boundary changes to keep all four Streatham wards together in one seat along with Clapham Town, Gipsy Hill and Knight’s Hill.

The proposals, unveiled today, were hailed as a victory by the Save Our Streatham campaign which opposed an earlier plan to carve up the wards.

These would have put Streatham Hill in Clapham Common constituency, St Leonard’s and Streatham Wells in Streatham and Tooting constituency and Streatham South in Merton-based Mitcham constituency.

The commission’s report said: "In light of the many strong representations that the Commission’s proposals would break local ties within Streatham, we have also decided that the four main Streatham wards should be kept together."

Save Our Streatham announced they had achieved their objective after 429 people signed their online petition as part of a wider campaign.

The group said: "Although these new proposals work well for Streatham, it is likely that others will be unhappy with the knock-on effects in their area.

"As a result they might oppose the proposals to keep the four Streatham wards undivided.

"And that is why we need you all to show your support for the revised Clapham and Streatham constituency."

Resident Tim Barnsley also called on people to respond to the commission’s consultation by saying the revisions were right for the area.

He said: "Streatham residents let the Boundary Commission know that Streatham needs a single strong voice.

"But the battle to keep Streatham together is not over yet."

The revised proposed changes show Clapham Common and Thornton remaining part of the constituency while Brixton Hill and Tulse Hill would become part of the Brixton constituency.

A spokesman for the office of Streatham MP Chuka Umunna said they believed the boundary changes were not in the best interests of Lambeth residents.

He said: "He will be voting against the proposals."

MP Umunna, Vauxhall MP Kate Hoey and Dulwich & West Norwood MP Tessa Jowell issued a joint statement against proposed boundary changes last year.

They said under the proposals Lambeth would be carved up with a disregard for borough boundaries and historic districts.

If the changes go ahead, they said: "We will see less representation in the future for one of the most deprived boroughs in the country."
