London, January 6 (RHC)-- British Prime Minster David Cameron has postponed a trip to Saudi Arabia, amid global outrage and rising tensions sparked by Riyadh's recent mass execution of people, including a top Shia cleric.

Starting with the Saudi capital, Cameron was set to begin a tour of the Persian Gulf states in the coming weeks, but according to UK daily The Times the trip has been postponed until March.

A Cameron spokesperson said that the premier's office will not confirm if the change in schedule is related to the executions of 47 people, including prominent Shia cleric Nimr al-Nimr, adding that the prime minster is currently focused on the renegotiation of the UK's presence in the European Union ahead of an upcoming referendum on the subject.
