Michael George Corbett Ashby, MRCP, FRCP (1 November 1914 – 10 December 2004) was a consultant neurologist at the Whittington Hospital, London and an expert witness for the prosecution in the failed trial of suspected serial killer John Bodkin Adams.
[2] In 1949 he was appointed consultant neurologist to the Whittington Hospital in north London, where he remained until his retirement in 1975.
He succeeded Macdonald Critchley as consultant neurologist to the Royal Masonic Hospital in 1965, also retiring from there in 1975.
In summing up, the judge called Ashby "the key witness", one "coming between the extremes", whose "border-line evidence" made it unsafe to convict.
The prosecutor, Reginald Manningham-Buller, withdrew the charge however by entering a nolle prosequi – partly because – in his words – the case would again be "based on the evidence of Dr Ashby".
