The SNP has accused a person who has persistently asked the Scottish Government for information of "wasting taxpayers' money on ridiculous fishing missions".

Deputy First Minister Nicola Sturgeon has revealed that one person was responsible for 13.5% of all Freedom of Information (FoI) requests to the Government.

The person submitted 85 requests, six of which went to internal review and one which went to the Information Commissioner for appeal, at a total cost of more than £23,000.

Ms Sturgeon, whose wide remit includes FoI legislation, was responding to a question by fellow SNP MSP Jamie Hepburn.

While the identity of the requester was not revealed in Ms Sturgeon's answer, First Minister Alex Salmond told Parliament last month that "a Labour researcher is responsible for over 14% of all Freedom of Information requests".

Ms Sturgeon said: "Our records show the anonymous requester referred to by the First Minister has submitted 13.5% of all of the requests received by the Scottish Government between the start of the summer recess on June 29 and November 6, 2012."

Mr Hepburn said: "Access to information is important but this one person is just wasting taxpayers' money.

"Everyone has the right to use Freedom of Information but there is also a responsibility to use it properly, not waste taxpayers' money on ridiculous fishing missions."
