In a discussion titled "British Intelligence", broadcast on 16 July 1988, the guests included Merlyn Rees, H. Montgomery Hyde and a man called Robert Harbinson, described by Francis Wheen in The Independent newspaper as follows:
Robin Bryans, a ... travel writer and sometime music teacher who also goes under the names Robert Harbinson and Christopher Graham. (His opponent) is Kenneth de Courcy ... who likes to be known as the Duc de Grantmesnil ...
Though both are Irish by birth, both have intelligence connections (Bryans was a friend of Blunt), both are ex- jailbirds and both are – how shall we say? – quite eccentric ... [Bryans] denounced de Courcy on the Channel 4 programme After Dark. His allegations are too confused (and too libellous) to be summarised here, but names such as Mountbatten, Shackleton, Churchill, Blunt seem to pop up often.[69]
