Politics and History of the constituency

From its inception Londonderry had a unionist majority, though by the 1970s the nationalist vote was approaching 40% in some elections.

In 1974 the Ulster Unionist Party repudiated the Sunningdale Agreement and so did not reselect Robin Chichester-Clark , who had been a Minister in the government of Edward Heath. Instead they ran William Ross, who held the seat until 1983. He was then elected for the new East Londonderry.
