Vodafone has revealed how government agencies around the world, including those in the UK, are spying on their citizens. In report that unveils the global extent of government surveillance, Vodafone said security services should not be snooping on people's data just because it is possible.The company said most countries its operates in need a warrant to intercept communications, adding that a small number of governments have direct access to its networks. Vodafone said while it makes every effort to protect customer privacy, it must comply with laws "designed to protect national security and public safety".The group called on authorities to amend legislation, which enables agencies and authorities to access an operator's communications infrastructure without the knowledge and direct control of the operator."In our view, it is governments - not communications operators - who hold the primary duty to provide greater transparency on the number of agency and authority demands issued to operators," Vodafone said. The UK government made 514,608 communications data requests and 2,760 interception requests to mobile phone operators in 2013.RD
