Prince Charles and the new king of Saudi Arabia have held informal talks today in a visit that some have argued could have a "significant" impact on UK-Saudi relations.
The Prince of Wales and King Salman spoke privately via an interpreter before a lavish meal in Riyadh - though it is not known whether Charles heeded calls to raise the plight of jailed blogger Raif Bawadi.
Amnesty International UK urged the future king to use his influence and intervene on behalf of Badawi - who was sentenced to 10 years in prison and 1,000 lashes after setting up a website for Saudi liberals and being accused of insulting Islam.
Charles knows the Saudi monarchy well and was among a number of world leaders who traveled to the country to pay respects after the death of Salman's predecessor King Abdullah.
Speaking ahead of the visit, Simon Collis, Britain's ambassador to Saudi Arabia, said the conversations between the pair could be significant, though he could not say "whether or not" Charles would raise the plight of Mr Badawi.
