Bob is the author of two chapters in the Oxford University Press publication on Financial Markets and Exchanges Law, covering UK recognised investment exchanges and clearing houses and alternative trading systems respectively. Bob gave evidence to the UK Parliamentary Commission on Banking Standards in relation to proposals for the ring-fencing of retail banking activities in the UK.
