Boundaries and boundary changes 1945–1983: The Urban District of Thurrock. The House of Commons (Redistribution of Seats) Act 1944 set up Boundaries Commissions to carry out periodic reviews of the distribution of parliamentary constituencies. It also authorised an initial review to subdivide abnormally large constituencies in time for the 1945 election. This was implemented by the Redistribution of Seats Order 1945 under which South East Essex was divided into two constituencies. As a consequence, the new Thurrock Division of Essex was formed, comprising the Urban District of Thurrock (created largely from amalgamating the Urban Districts of Grays Thurrock and Tilbury and the Rural District of Orsett). 1983–2010: The Borough of Thurrock wards of Aveley, Belhus, Chadwell St Mary, East Tilbury, Grays Thurrock North, Grays Thurrock Town, Little Thurrock, Ockendon, Stifford, Tilbury, and West Thurrock. Northern areas transferred to the new County Constituency of Billericay. 2010–present: The Borough of Thurrock wards of Aveley and Uplands, Belhus, Chadwell St Mary, Chafford and North Stifford, Grays Riverside, Grays Thurrock, Little Thurrock Blackshots, Little Thurrock Rectory, Ockendon, South Chafford, Stifford Clays, Tilbury Riverside and Thurrock Park, Tilbury St Chads, West Thurrock, and South Stifford. Following a redistribution of local authority wards, East Tilbury was transferred to the new County Constituency of South Basildon and East Thurrock.
