There will continue to be two parliamentary constituencies for Milton Keynes, but these will be formed on a North/South basis, effectively abolishing the existing arrangement.
The expanding population of Milton Keynes led to this constituency being divided for the 1992 general election into two parts (Milton Keynes South West and North East Milton Keynes). The new North East constituency was taken by Peter Butler of the Conservatives, who lost it to Labour's Brian White at the 1997 election. White held the seat until 2005, when it was regained by the Conservatives' Mark Lancaster.
