'by some very prominent Politicians' - 

At the risk of being dragged off to the Tower, 'names in the frame' from my friend at Westminster are currently Willie Whitelaw, William Waldegrave and Michael Portillo.

Of course we all know about the late Lord Mountbatten's 'involvement' in the boys' home scandal in Ireland in the 70's that was covered-up in the UK.
