Michael Platt Winstanley, Baron Winstanley (27 August 1918 – 18 July 1993) was the Liberal Member of Parliament (MP) for Cheadle from 1966 to 1970 and, after boundary changes, for Hazel Grove, a newly created seat comprising half his former seat, from February to October 1974.

[2] He graduated in medicine and served in the RAMC before becoming a general practitioner in Urmston.

Following his return to the House of Commons in 1974, Winstanley discovered that he held a post which would disqualify him from being a member of the House of Commons, medical officer at a Royal Ordnance Factory that amounted to employment in the Civil Service of the Crown.

Winstanley's daughter, Diana, became a highly respected academic and teacher at Kingston University, where bursaries are offered in her memory.
