The south of the constituency has been seen as a site for building large entertainment centres on Rainham's large marshland area, and was viewed as a potential site for the European Disneyland project, although it was considered much less suitable than the current position near Paris. There have been plans to build a casino but permission is yet to be granted. Hornchurch is a predominantly suburban and Conservative-voting area, but the seat is seen as a swing seat due to Rainham and Elm Park's working class voters and because the wealthiest Emerson Park area of Hornchurch does not form part of the constituency, instead forming part of Upminster constituency. The Conservative Robin Squire was elected to Parliament as the member for Hornchurch on 3 May 1979, in one of the most surprising results of that election. Labour-held Hornchurch had not been a marginal seat and Squire had not expected to win it. However, he gained the seat from Alan Lee Williams with a majority of just 769 on a "freak" swing of 8.5% to his party. During the Thatcher years Squire was considered to be a prominent "wet", opposed to the Conservative government's economic and employment policies. After Mrs Thatcher left office in 1990, Squire's political position strengthened and he held junior ministerial posts until the fall of the Major government in 1997. Squire was defending a majority of 9,165 - his personal popularity plus his prominence as a Minister led him to believe that he would hold the seat, but he lost to Labour's John Cryer with a 16% swing and a Labour majority of 5,680. Squire stood against Cryer again in the 2001 general election but was again defeated by a significant majority. The constituency was abolished for the 2010 election. The areas of the constituency covered by the Elm Park, South Hornchurch, and Rainham and Wennington wards in the London Borough of Havering were merged with Dagenham to form a cross-borough Dagenham and Rainham constituency. Hacton and St Andrews wards in Hornchurch merged with Upminster to form Hornchurch and Upminster. Hylands ward in Hornchurch merged with Romford. Prior to the change in boundaries the new seats were predicted to be marginal Labour and safe Conservative respectively if they followed the voting patterns of the previous Dagenham, Upminster and Romford constituencies.
