“The trouble with the Yes campaign is they are looking at Britain as having an immature, childish and petty veneer,” Rowling explained.
“But if we wrap it a sleeker, more adult looking cover they may just get it.
“I’m not suggesting anything drastic. In fact I’d keep the contents of the union exactly the same, but maybe taking the red white and blue from the Union Flag and replacing them with more charcoal hues will give it an air of respectability.”
Alex Salmond was quick to criticise Rowling’s support for the ‘No’ campaign.
“I don’t think it will ever be acceptable for anyone to be seen on a train, proudly being British just because it looks more grown up.”
However Rowling remained optimistic about the future of Britain and the ‘Better Together’ message.
“If making the cover more adult doesn’t work we can turn the story of Britain into an eight movie series. I have to get my £1m back somehow.”
