Former CIA employee Edward Snowden, who leaked confidential data about numerous global surveillance programmes, will deliver a keynote speech at this year’s IP EXPO Europe.

Said to be Europe’s number one IT event, this year’s IP EXPO will take place at London’s ExCel where Snowden will share his opinion on the implications of existing national cyber security.

Renowned BBC journalist Andrew Neil will interview Snowden, who will join the event via satellite, and will share his views on current state of cyber security worldwide.

Snowden is expected to shed some light on web privacy and the implications of recent major security breaches, along with his views on the future of cyber and national security.

He is also expected to present his views on the UK Government’s Investigatory Powers Bill, or ‘Snoopers’ Charter’, which faced criticism due to the power it gives to watchdogs.

As per the bill, ISPs and mobile network operators are asked to track individual users’ browsing activity for over a 12-month period.

IP EXPO Europe director of strategy Bradley Maule-ffinch said: "Our security is increasingly under threat and, following recent events like the Hacking Team breach, there are fresh concerns about how safe we really are on the Web.

"It’s a global issue, one which was bought to the forefront of the news agenda by Edward Snowden in 2013. For that reason, we are very excited to welcome him to this year’s IP EXPO Europe and hear his views on the matter."
