The word 'landslide' is over-used in elections, but that's what happened in Southampton. The Tories were defending 14 seats, and lost 10 to Labour. Labour also won a seat from Lib Dems. This was one of Labour's top target councils. Conservatives were defending controversial record of council cuts.
The Conservatives are out in front in this unitary authority. The other main parties are keen to make inroads.
