Germany's biggest telecoms company is to follow Vodafone in disclosing the number of surveillance requests it receives from governments around the world.
Deutsche Telekom, which owns half of Britain's EE mobile network and operates in 14 countries including the US, Spain and Poland, has already published surveillance data for its home nation - one of the countries that have reacted most angrily to the Edward Snowden revelations. In the wake of Vodafone's disclosures, it announced that it would extend its disclosures to every other market where it operates and where it is legal.
A spokeswoman for Deutsche Telekom, which has 140 million customers worldwide, said: "Deutsche Telekom has initially focused on Germany when it comes to disclosure of government requests. We are … checking if and to what extent our national companies can disclose information. We intend to publish something similar to Vodafone."
Mobile companies have been reluctant to discuss the extent of their cooperation with national security and law enforcement agencies.
