Human Rights Activists protest at Downing Street and urged Theresa May to withdraw the invitation to Crown prince Mohammed Bin Salman of Saudi Arabia
The powerful heir to the throne is set to arrive in London on Wednesday for three days of talks with Prime Minister Theresa May, Foreign Secretary Boris Johnson and the royal family.
As Prince Mohammed and Prime Minister Theresa May meet, demonstrators will protest both countries’ roles in Yemen where war has killed an estimated 10,000 people and where 8.3 million people depend on food aid and 400,000 children have life-threatening levels of malnutrition.
Rights campaigners including the Campaign Against Arms Trade have denounced the visit due to Riyadh's human rights record and the Saudi-led military intervention in Yemen.
Ten groups plan on taking part in the protests, including the Stop the War Coalition and Organization for Human Rights in the UK.
The UK has increased its weapons sales by around 500 percent since the onset of the Saudi invasion.
Anti-arms trade campaigners say the opaque open licences, which include spare parts for strike aircraft as well as missiles, play a deadly role in the conflict as they are key to keeping the Saudi air force in the air above Yemen.
Saudi Arabia is also notorious for its attempts to spread extremism all around the world including UK.
Riyadh is the chief foreign promoter of extremism in the UK, a new report of the Henry Jackson Society said.
According to this report, there was a "clear and growing link" between extremist organisations in receipt of overseas funds, hate preachers and radical groups promoting violence.
