Witham is a parliamentary constituency in Essex represented by Dame Priti Patel in the House of Commons of the UK Parliament since its 2010 creation.

Witham itself is an industrial town, on the Great Eastern main line railway from London to Norwich, with some heavy industry and London commuter belt residential areas – the strength of the Labour vote here was just enough to turn the former Braintree seat red in 1997, and in 2001, on the previous boundaries.

However, the town is small, and the Witham seat extends to cover a huge part of rural central Essex, with affluent commuter villages and farming communities that show high levels of Conservative support.

The seat was created for the 2010 general election following a review of the Parliamentary representation of Essex by the Boundary Commission for England which resulted in radical alterations to existing constituencies to allow for an extra seat to be created due to increased population.

As a consequence, the new seat of Witham was created which included parts of the constituencies of Braintree, Colchester, North Essex, and Maldon and East Chelmsford.
