Britain and the US are considering boycotting a major international conference in Saudi Arabia after the disappearance Saudi journalist Jamal Khashoggi, the BBC has learned.
Mr Khashoggi, a critic of the Saudi government, vanished on 2 October after visiting its consulate in Istanbul.
The authorities in Istanbul believe he was murdered there by Saudi agents – claims Riyadh has dismissed as “lies”.
Donald Trump has said he would “punish” Saudi Arabia if it was responsible.
A number of sponsors and media groups have decided to pull out of this month’s investment conference in Riyadh, dubbed Davos in the Desert, as a result of concerns over Mr Khashoggi’s fate.
Diplomatic sources have now told the BBC’s James Landale both the US Treasury Secretary, Steve Mnuchin, and the UK’s International Trade Secretary, Liam Fox, might not attend the event.
A joint statement of condemnation is also being discussed by US and European diplomats if it is confirmed that Mr Khashoggi was killed by Saudi agents.
