In an analysis of the voting trends at the 1970 general election, published shortly after the event, political scientist Richard Rose claimed that Jennie Lee's defeat in Cannock was "the biggest upset" of the contest. Rose believed that a large expansion in the electorate in the constituency contributed towards the 10.7% Labour to Conservative swing, which was significantly higher than the national average.
