A Downing Street spokesperson said:
The Prime Minister spoke to King Salman today (24 October) to reiterate the UK’s grave concerns about the murder of Jamal Khashoggi in the Saudi consulate in Istanbul.
The Prime Minister said the current explanation lacks credibility so there remains an urgent need to establish exactly what happened. She strongly urged Saudi Arabia to cooperate with the Turkish investigation and to be transparent about the results. It is important that the full facts are established.
The Prime Minister also reiterated that all individuals bearing responsibility for the killing of Mr Khashoggi must be properly held to account.
She said the Home Secretary is taking action against all suspects in the murder of Mr Khashoggi to prevent them entering the UK. If these individuals have visas, they are being revoked.
