The figures were given by the government yesterday. The paper reports Stephen Byers, Labour MP for Wallsend, as calling for a limit to class sizes. He said the increase was unacceptable - the number of children affected is at its highest level since the 1970s.
Kingston and Redbridge LBCs have the highest number of classes with 30 or more children, closely followed by Trafford, Tameside and Rochdale.
The lowest proportion of such classes are to be found in Kensington and Chelsea, Haringey, Tower Hamlets, Lambeth and Hackney.
