Google's handling of "right to be forgotten" requests from European citizens was not exactly what the European's privacy watchdogs wanted, as the search engine restricted the removal of Internet links to European sites only. European data protection authorities are meeting representatives of Google, Microsoft and Yahoo to discuss the implementation of the recent ruling from Europe's top court upholding people's right to request that outdated links be removed from Internet search results.

European Union privacy watchdogs have concerns on the way the ruling, which has pitted privacy advocates against free speech defenders, is being implemented, particularly by Google.

Regulators can take Google to court if it refuses to meet their demands, as happened in Spain where the "right to be forgotten" ruling originated.

Google has decided only remove results from its European search engines, such as google.co.uk, meaning anyone can easily access the hidden information by switching to the widely used google.com.

Experts have said this effectively defeats the purpose of the ruling.

Another issue likely to be raised by the EU watchdogs is Google's decision to notify the owners of the websites that have been removed from search results.
