Miliband's image improves, but still behind Cameron on key leadership qualities
Although he trails the Prime Minister on most aspects and is lowest of the three leaders on likeability, Ed Miliband's image has improved since last December, especially when it comes to understanding the problems facing Britain
Cameron has clearest vision for Britain, most capable and best in crisis but also seen as out of touch
Nick Clegg is seen as likeable but also more style than substance
