The international press freedom group, Reporters Sans Frontières (RSF), has written to foreign secretary Boris Johnson to air concerns about his current visit to Saudi Arabia.

It urges Johnson to take up the case of jailed blogger Raif Badawi along with the plight of other journalists detained by a regime with one of the world’s worst press freedom records.

Saudi Arabia is ranked at 165th of 180 countries in RSF’s world press freedom index, noting that there are no really free media in a country where “all journalists censor themselves.”

The letter to Johnson, signed by RSF’s secretary general, Christophe Deloire, calls on Johnson to take up the “dire press freedom climate in the country at the highest possible levels during your visit.”

Saudi Arabia’s king, Salman bin Abdelaziz Al Saud, has been on RSF’s list of “predators of press freedom” since he succeeded his brother Abdullah as king in 2015. He is said to embody “the heritage of a dynasty that has always been hostile to media freedom.”

At least 10 journalists and citizen journalists are currently jailed in Saudi Arabia on a range of charges, such as harming the king’s image and reputation, blasphemy, insulting religion, and “inciting chaos.”

RSF points in particular to the case of Badawi, the co-founder of an online discussion forum, the Liberal Saudi Network, who has been in jail since June 2012.

He was convicted in May 2014 of insulting Islam and sentenced to 10 years in prison, plus 1,000 lashes and a 10-year ban on travelling abroad after the completion of his prison sentence,.

Badawi’s flogging was widely condemned internationally, including by the the foreign office. An international outcry followed the administration of the first 50 lashes. Thus far, the rest of the sentence has not been carried out.

His wife, Ensaf Haidar, has been fighting to keep his case in the public eye. She was granted asylum in Canada, where she lives with the couple’s three children.

Badawi’s lawyer, Waleed Abu Al Khair, has been in jail since 15 April 2014. He was sentenced to 15 years in prison in July 2014 on a variety of charges.

At least eight other journalists and citizen journalists are currently in prison in Saudi Arabia. They include Zuhair Kutbi, (held since July 2015); Fawzan Al-Harbi, (June 2014); Jassim Mekki A’al Safar (June 2014); Alaa Brinji (May 2014); Fadhel Al-Manafes (April 2014); Wajdi Al-Ghazzawi (February 2014); Ali Jaseb Al-Touhifah (August 2012); and Jalal Mohamed Al-Jamal (February 2012).

Johnson has also been urged by fellow Conservatives not to brush aside human rights concerns.
