It beggars belief that Cameron didn't know

News that David Cameron's own constituency party has had to return £7400 in illegal donations surely calls for an apology to the House of Commons. Francis Maude told the Commons on 4 December: "our donations have been properly made and properly declared, and all have been made by permissible donors." I trust that Maude will now apologise for misleading the House. After all, in the immortal words of Mr Cameron, it 'beggars belief' that he didn't know what his own constituency party was up to. And surely he would have shared such knowledge with his colleague before allowing him to mislead the House?
