Great Easton is also home to the Opera Minima, which is an opera/theatre group registered as a charitable trust and based at the Old Corset Factory in the village and is sponsored by Leicestershire County Council, Harborough District Council, Creative LeicesterShire and the Welland Sub-Regional Strategic Partnership.
Great Easton is in the Nevill Ward of Harborough District Council and is represented by Cllr Michael Rickman (Con).
In 2003 Great Easton was visited by the archaeological television programme Time Team and the finds included 14th-century pottery, a brick surface thought to be related to the village's old slaughterhouse and a Chinese "cash coin".
