Castle Point.
Conservative and Unionist Party MP Rebecca Harris holds the seat on 38.1% of the vote.
1 Jun 2026
As Conservative Chief Whip -- appointed by Kemi Badenoch in November 2024 -- Rebecca Harris holds one of the most demanding roles in opposition politics, responsible for managing party discipline and parliamentary strategy. That role explains her most visible recent act: voting with the Conservative majority to refer Prime Minister Starmer to the Privileges Committee over the Mandelson appointment, a move that puts her squarely at the centre of the opposition's current accountability push. On the Pension Schemes Bill, she voted twice against the government's reserve power to direct pension fund investments -- consistent with her above-party-average concern for pension protection -- and she backed the Lords' positions on multiple English Devolution Bill amendments.
Harris votes with her party on every recorded division -- a 100% alignment rate -- and participates in 79% of votes, broadly in line with the Commons average. Her stance profile reflects standard Conservative positioning: strongly pro-business (90%), tough on crime (85%), and resistant to tax increases (87%), while sitting well below the party average on workers' rights (7%) and progressive taxation (3%). She is notably more sympathetic to Lords scrutiny than her party average, backing their positions consistently on the devolution legislation.
Outside the chamber, local news from the past 90 days shows active constituency work: she lobbied for three years to secure a banking hub for local residents, visited a traffic-light failure site during rush hour, and engaged with a Castle Point care home. Her speech activity -- six contributions across three debates, with the last recorded in October 2024 -- reflects the reality that the Chief Whip's work happens largely behind the scenes, which limits the available parliamentary record.
