[9] The Amber Valley constituency is located in the east of Derbyshire, and covers the market and manufacturing towns of Alfreton, Heanor and Ripley; in a majority of council elections from 1960 to 2012, these were favourably disposed to the Labour Party.

The constituency's generally small majorities and bellwether status since 1983 (being won by the party that nationally holds the most parliamentary seats) means Amber Valley was, by most common measures, a marginal seat, with a reputation for political volatility, with periodic large swings towards both the Conservative and Labour parties.
