Sales of British defence and security equipment to Saudi Arabia are under scrutiny as the Kingdom wages war on Houthi rebels in neighbouring Yemen.
Campaigners against the UK arms trade are calling for an immediate ban on sales after the country privately admitted to bombing a funeral. More than 140 people were killed in the missile strike, a further 500 were left injured.
But just what is being sold and how much is the industry worth to the British economy?
According to the Guardian:
"[The UK] now has about 12% of the global defence export market and, over the last decade, has shored up its position as the second largest arms exporter in the world."
Forces TV's Kate Gerbeau spoke to Oxfam's senior policy advisor about regulation and the UK arms trade - just click below to watch.
The Office of National Statistics listed UK GDP for 2015 as £1.833 trillion, making arms sales for that year about 0.42% of the total.
To put that in perspective, annual defence spending accounts for just over 2%
- meaning like them or not, arms sales are a significant part of the UK economy.
