In June 2019, he was awarded an honorary scholarship at the London Zoological Society. In October 2009 "The Sunday Times" reported that Lord Paul had been unable satisfactorily to explain claiming expenses of £38,000 for the period January 2005 to July 2006. Lord Paul immediately requested the Clerk of the Parliaments to investigate his expenses at the same time repaying, £41,982 instead of £26,988 – £15,000, more than the House of Lords would have requested at the conclusion of their investigation. A refund of the difference was never issued by the House of Lords. The Metropolitan Police opened an investigation concerning these expense claims, but by the end of February 2010 concluded there was no case. Lord Paul appeared before various committees for Lord's Conduct with ultimately the Privileges Committee concluding that Lord Paul had not acted dishonestly or in bad faith. They did determine however that he had been negligent and acted in ignorance and that his actions did render him liable to sanction by the House." Lord Paul's suspension was for four months. Lord Paul completely disagreed with their finding, calling it "unreasonable." Lord Paul gave a Speech in the House of Lords in June 2011 calling for reform and revision of the structure of the constitution. Paul tendered his resignation as Deputy Speaker to the Lord Speaker on 1 November 2010. His letter, printed in "The House Magazine" a week later, expressed his reservations about the process, calling it "a sad saga for parliamentary democracy – an unfortunate series of events having evidently been inspired by the electoral politics of the media". He has spoken on this topic many times since the expenses scandal initially made news, and maintains that no wrongdoing had occurred in his case. Lord Paul is on the Sunday Times Rich List as the 38th richest person in Britain, although he claims to take public transport in London "like everybody else". Since the 1960s he has lived in Portland Place, in central London. He and his family own a dozen flats in the block, each one worth close to a million pounds. He also has a country estate, in Beaconsfield, Buckinghamshire. His son Angad Paul, CEO of Caparo plc, died after falling from his Marylebone penthouse flat on 8 November 2015. A police statement stated they considered there to be no suspicious circumstances.
