South Leicestershire is a constituency represented in the House of Commons of the UK Parliament since 2015 by Alberto Costa, a member of the Conservative Party. The current constituency has similar boundaries to the previous Blaby constituency. Historically the "Southern Division of Leicestershire", was a county constituency, less formally known as South Leicestershire. From 1832 to 1885 it elected two Members of Parliament (MPs) by the bloc vote system of election.
