Tories saw a big swing to Labour in a by-election for their flagship Wandsworth Council.The majority was slashed in Thamesfield, Putney – in contrast to earlier trends in other Conservative strongholds.
The Wandsworth by-election is the borough’s first for 12 years, the previous such contest being in the last century. It was caused by the resignation of former council leader Edward Lister after his appointment as chief of staff to London Mayor Boris Johnson. Analysis of 24 comparable results in June suggests a 1.4% projected nationwide Labour lead over Tories.
A calculation based on 11 wards fought both times by all three major parties gives a line-up of Labour 38.2%, C 38.1%, Lib Dem 13.7%. The calculations of projected party leads and vote shares are based on general election figures for wards last fought in 2010.
The basis for seats previously contested in other years is statistics published by the BBC after main council polls. These have tended to be close to other published surveys.
