'Drink driving': Guy Pelly, pictured today outside court, denied driving his black Audi TT while over the legal limit A close friend of Prince William has claimed a drink driving charge against him could be invalid because of malfunctions in a police breathalyser machine. Guy Pelly, 32, was pulled over in his £90,000 black Audio R8 last year, and tests found that he was significantly over the legal alcohol limit. He is currently standing trial in Westminster Magistrates' Court, which heard today that a reading showed the proportion of alcohol in Mr Pelly's breath was 52 microgrammes in 100 millilitres of breath.
