The government is currently refusing to disclose details of private meetings between David Cameron and Conservative party donors, following the Cruddgate debacle.
Maude, the Cabinet Office minister, has stated that demands for lists of visitors
to Cameron's flat in Downing Street are unreasonable. The Tories are sticking to the line that Cameron's flat is used as his family home and the prime minister foots the bill, not the taxpayer, therefore these dinners etc are private.
That is fair enough IF the people who visit Cameron in his flat are visiting him as David Cameron "friend/acquaintance", rather than as David Cameron leader of the Tory party/Prime Minister.
It's not just what you do, but what your are seen to do and who you do it with that counts.
BTW, who paid for the renovation of the flat that Cameron and family occupy rent free?
Oh yes, that would be the taxpayers!
