Former Pakistan Prime Minister Imran Khan and his wife Bushra Bibi have been sentenced to further jail terms following a fraud case involving state gifts.

They were convicted of breaking Pakistan's rules on gifts after Bibi was given a luxury jewellery set by Saudi Arabia's Mohammed bin Salman during a 2021 state visit.

The pair are already serving time in prison for earlier convictions, and the new sentences - 10 years for criminal breach of trust and seven years for criminal misconduct, and a fine - will reportedly run concurrently to their earlier terms.

Khan has described the charges as politically motivated and his lawyer told BBC News his team plan to challenge the verdict.
