 The seat has become even safer due to the boundary changes in 2010, which removed the three most Labour inclined wards in Bromley borough, centered on the town of Penge, replacing them with more rural - and Conservative - areas surrounding Hayes, Bromley Common and Keston.Since 1983 there has been a close contest for second place between Labour and the Liberal Democrats.Labour's share has remained much greater than in Orpington whereas the Liberal Democrat share has remained much greater than in Croydon Central.
