Sir Idwal Vaughan Pugh KCB (10 February 1918 – 21 April 2010) was a civil servant who was Permanent Secretary at the Welsh Office and distinguished himself as Parliamentary Commissioner for Administration and Health Service Commissioner for England, Scotland and Wales (Parliamentary and Health Service Ombudsman).

He was raised by relatives Thomas and Mary Vaughan in Ton Pentre in the Rhondda Valley and educated at Cowbridge Grammar School.

He won an Open Scholarship to study Mods and Greats at St John's College, Oxford and graduated in 1940 whereupon he joined the Army.

Pugh joined the Ministry of Civil Aviation as an Assistant Principal in 1946, where he organised supplies and chartered aircraft for the Berlin Airlift.

In this spirit, Pugh modified the filter system that required members of the public to take their complaints to the Ombudsman through their MPs.

Twenty-five officers were found to have been treated similarly and the Director of Public Prosecutions considered whether charges should be brought against the officials concerned.

Such was the public outcry, the Secretary of State for Social Services David Ennals was forced to apologise and new rules were established that forbade civil servants from denying a claimant their entitlement when owed money by a government department.

Pugh maintained that parents were being told everything as far as was reasonably possible and that the report could be used to place pressure for compensation for children who suffered brain damage as a result of vaccination.

[10] When Pugh handed over to his successor, he urged civil servants to take note of the mounting complaints from the public about their 'rudeness and oppressive behaviour'.

[1] After stepping down from the post of Ombudsman in 1978, Pugh worked in the City as a director of Standard Chartered Bank and the Halifax Building Society.

Pugh also assumed academic posts, serving as Chairman of the Royal Northern College of Music from 1988 to 1992 and President of Coleg Harlech between 1990 and 1998.

To his delight, he was made an honorary Fellow of St John's College and he moved from Cardiff to Oxford, taking a university course in composition.
