A political party founded in 1951 in Redruth, dedicated to re-establishing a degree of autonomy in Cornwall, the south-westernmost county in England. Also known as MK, (translates as 'Sons of Cornwall'), the original aims of the MK were primarily socio-cultural. Currently their philosophy is: 'Cornish, Green, Left of Centre, Decentralist'.
They won their first seat at local level on Redruth-Camborne Urban Council in 1953. A schism in the early 1970s led to the formation of the Cornish Nationalist Party.
