Watford constituency and the Welwyn Hatfield borough ward of Northaw and Cuffley, which is currently included in the Broxbourne constituency, join Hertsmere. The effect will be to reduce the population of the constituency by approximately 7%: the new Hertsmere constituency is predicted to contain an electorate of approximately 73,133. On 8 November 2022, the final draft of the Boundary Commission's proposals was published, following consultation. The new Hertsmere CC (County Constituency) is as proposed in the previous draft. Members of Parliament This safe Conservative constituency was created in 1983 from the former seat of South Hertfordshire. Cecil Parkinson, who had entered Parliament in 1970 and had previously represented South Hertfordshire, was MP from the seat's creation until his retirement in 1992. Parkinson was a close ally of Prime Minister Margaret Thatcher and had run her successful 1983 election campaign. Parkinson stepped down on the day of Margaret Thatcher's resignation as Conservative party leader. James Clappison held the seat for five electoral terms, from 1992 until his decision to stand down from parliament at the 2015 general election. The seat was subsequently won by Oliver Dowden.
