Cheltenham () is a constituency represented in the House of Commons of the UK Parliament. As with all constituencies, the constituency elects one Member of Parliament (MP) by the first past the post system of election at least every five years. Boundaries and boundary changes 1885-1918: The existing parliamentary borough, and so much of the parish of Charlton Kings as lay to the north of the railway from Cheltenham to Banbury. 1918–1950: The Municipal Borough of Cheltenham and the Urban District of Charlton Kings. 1950–1983: As 1918 but with redrawn boundaries. 1983–1997: The Borough of Cheltenham, and the Borough of Tewkesbury wards of Leckhampton with Up Hatherley, Prestbury St Mary's, and Prestbury St Nicolas. Leckhampton, Up Hatherley and Prestbury were added to the seat from the Cirencester and Tewkesbury constituency; they had previously been in the abolished Cheltenham Rural District. 1997–2010: The Borough of Cheltenham wards of All Saints, Charlton Kings, College, Hatherley and The Reddings, Hesters Way, Lansdown, Park, Pittville, St Mark's, St Paul's, and St Peter's. Leckhampton, Up Hatherley and Prestbury were transferred to the new Tewkesbury constituency; they had been incorporated into the redrawn Borough of Cheltenham in 1991. 2010–present: The Borough of Cheltenham wards of All Saints, Battledown, Benhall and The Reddings, Charlton Kings, Charlton Park, College, Hesters Way, Lansdown, Leckhampton, Oakley, Park, Pittville, St Mark's, St Paul's, St Peter's, Springbank, Up Hatherley, and Warden Hill. Leckhampton and Up Hatherley were transferred back to this seat from the Tewkesbury seat. As its name suggests the constituency is based on the town of Cheltenham in Gloucestershire, covering a different, slightly smaller area than the borough of the same name. It is bordered by the Tewkesbury and Cotswolds seats. Constituency profile Famous for its racecourse which hosts the annual Cheltenham Gold Cup in March, with a long-established girls' school and right at the edge of the Cotswold Hills, Cheltenham has a large tourism sector. GE Aviation is a large employer and GCHQ, the government communications centre, is here, so numbers of highly skilled workers and professionals (47.5% in the year ended September 2014) are well above the national average (44.6%). One of the West of England's most upmarket towns, the few neighbourhoods of medium levels in the Index of Multiple Deprivation are almost wholly in Hester's Way ward which has the most social housing. About 10% of the electorate are students at the University of Gloucestershire just outside
