The wife of Zimbabwean President Robert Mugabe has been granted immunity over an alleged attack against a British photographer in Hong Kong, according to a report on the BBC.

Photographer Richard Jones says he suffered cuts and bruises after Grace Mugabe punched him while wearing a diamond-studded ring on 15 January.

He says he was taking photos of 43-year-old Mrs Mugabe near a luxury hotel for the Sunday Times newspaper.

Mrs Mugabe is immune under Chinese diplomatic rules, officials said.

Mr Jones had been working on a report about Mrs Mugabe's "extravagant holiday in the Far East that was in stark contrast to the lifestyle of the people of Zimbabwe", according to an article on the Times website.
