The Defence and Security Equipment International (DSEI) weapons conference at the ExCeL Centre in the London Borough of Newham - not far from the Olympic Park - is the largest arms fair on the planet, featuring state-of-the-art vehicles, firearms, protective equipment and communications technology.
Its website describes it as a 'must-attend' event that 'brings together the entire defence and security industry to source the latest equipment and systems, develop international relationships, and generate new business opportunities.

The arms fair 'provides a unique opportunity for government ministers, senior civil servants and all politicians with an interest in UK defence and security exports to see this vitally important industry in action', the website says.
James Cook of The Kernel was one of the few journalists allowed to attend the event.
He described it as 'one of the most secure places in the world' and said there are five different security checks and a large number of armed police.
'DSEI is home to a mind-boggling array of weaponry. Missiles, assault rifles and drones are all on show,' Mr Cook said.

Protestors say the arms trade fuels misery throughout the globe
'I ask my handlers what kind of people attend a weapons conference and they look mildly uncomfortable, before eventually telling me that as well as representatives of foreign governments, there are also private defence contractors shopping for weapons.
'Weapons dealers and exotically-dressed army officers examine rifles in detail, pulling triggers, staring down barrels and occasionally making “pow” noises before they place them back on the perspex rack.'
The biennial event draws a large crowd of protestors who object to arms dealers being able to display their wares on British soil.
