Do let the forum know if you receive a reply.
(I thought I heard on a BBCR4 speaking voice program that many FOI requests are denied for being too expensive/wasteful of bureaucratic time).
Last year York council were reprimanded by the information commissioner when one citizen took offence to his foi request being denied and branded trivial by the council. They were fined and forced to hand over the data. So it can be done if it's in the public interest.
I'm going to write to Jesse Norman with that letter enclosed asking for them.
As an FoI request.
