Twitter said government requests for user data and content removal jumped in the second half of 2014, especially in Russia, Turkey and the US.
In its twice-yearly transparency report, Twitter said it received 84 per cent more requests for content removal and 40 per cent more requests for account information from governments worldwide from July 1 to December 31, compared with the first six months of the year.
The report is part of a broader effort by the San Francisco-based company to shed light on government surveillance of its members. Twitter last year filed a lawsuit against the US government, claiming that restrictions on the information the company makes public about surveillance demands violate free-speech rights.

Turkey led in requests for tweet takedowns in the recent six-month period, the report said. The Turkish government issued 477 requests to remove content from the microblogging site in the period, a rise of 156 per cent from the prior six months.
