London East was a constituency that elected a single Member of the European Parliament (MEP). It was created in 1979 and abolished in 1999 when it was replaced by the multi-member London constituency. The European constituency was formed by the grouping of nine parliamentary constituencies used for the elections of members of the UK House of Commons: Barking, Dagenham, Hornchurch, Ilford North, Ilford South, Newham North East, Romford, Upminster and Wanstead and Woodford. The same boundaries were used in 1984, 1989 and 1994. Wikipedia page [1] refers.
