There's only ever been five chief execs at the PL:-
Rick Parry (dipper)
Peter Leaver
Richard Scudamore
Susan Dineage
Richard Masters
I had no memory of Leaver so looked him up on wiki, I couldn't help noting the irony of his bio...
He was educated at Aldenham School and Trinity College Dublin. He was a deputy High Court judge from 1994 to 2017, and was Chairman of the London Court of International Arbitration from 2008 to 2012.
Apparently he was hounded out by the red cartel because he had some decent qualities, like integrity, professionalism and honesty and wouldn't be their puppet.
