Gareth Jones, 36, was convicted after the bizarre incident in central London.

A paramedic who tried to rouse a drunken Jones, passed out in his clerical frock, was treated to expletives and a growled threat before the man of God assaulted him.

He had reportedly consumed around 53 units of alcohol beforehand.

When a police officer intervened, Jones began to yell that he had diplomatic immunity, according to the Mirror.

Recalling the exchange in court, prosecutor Edward Aydin said: “The officer says ‘which embassy?’ and he says: ‘The Vatican, you’re f**ked.’

“He is growling, makes no attempt to respond to a caution, and continues to shout that he has diplomatic immunity.”

Mr Aydin added: “I’m not sure if he has anything to do with the Vatican because he is with the Church of England.”

Jones was ordered to pay £700 in fines, £200 compensation to the police officer, £200 compensation to the paramedic, £85 prosecution costs and a £35 victim surcharge.
