Gordon Brown and open government

Open government and the Freedom of Information Act mean nothing, nada, zilch to the bunch of ... that rule us. Take a read of this from Christopher Hope in the Telegraph blogs. He's been trying to get Gordon Brown to release the names of those people entertained (at taxpayers expense) at Chequers since Gordon Brown became Prime Minister. So far Gordon Brown and his office have dodged the question; why? Even Tony Blair eventually made this information public, maybe Gordon's invitees are more embarrassing, what secrets do the names hold?
