Gordon will have bitten his nails to the quick after reading the Guardian this morning. Ronnie Cohen praises Cameron and criticises government policy – this from the man who has in the past given Labour £1.8m.

Asked what has gone wrong for Gordon, he is quoted as saying “All of a sudden what looked like a one-horse race is now a two-horse race.”

How does Ronnie feel about David Cameron becoming the next PM? “I am a businessman who supports a political party for two reasons: whether it supports entrepreneurship and social investment. If you said to me today, am I concerned about the possibility that a Conservative government would come back in and overturn the entrepreneurial system that we’ve worked so hard to do or seriously break the growth of social investment, I’d say no.” So Ronnie is now a swing voter.

Ronnie, who founded venture capitalists Apax Partners, doesn’t think much of Darling’s back-of-an-envelope plan to hike capital gains taxes 80% “Entrepreneurs need to recruit executives who know how to run a business. They’re on big salaries with big companies that offer pensions. A 10% rate enables someone with a big income to take a chance and work with an entrepreneur.” So will he actually be voting Labour this time?
