Further to my last posting, I just came across this on the BBC Website.
The bit that stood out for me was this:
but Tory treasurer Jonathan Marland says he is not prepared "under any circumstances" to disclose where his party's loans come from.
Then don't complain! There is a difference between being honest and asking pertinent questions, like many in the Labour Party, and being critical for political advantage when the Conservative Party's house isn't in order.
