Norwich South is a constituency in Norfolk represented in the House of Commons of the Parliament of the United Kingdom,[n 1] since 2015 by Clive Lewis, of the Labour Party.

At the 2010 election, the seat was considered a three-way marginal between the incumbent Labour party, the Liberal Democrats and the Conservatives.

The Liberal Democrats won the seat, with the lowest percentage share of the vote in a constituency in the 2010 election.

The loss was considered an embarrassment for the Labour Party as it was the seat of a former Home Secretary.

In the 2015 election, Norwich South was one of the Green Party's target seats, and due to the tiny majority of just 310 votes for the Liberal Democrat Simon Wright over Labour in the previous election, it was a key Labour target.
