Opinium polling - Cameron's lead over Corbyn not shared by his successors

George Osborne may be the betting favourite to be the next prime minister when David Cameron retires but he is also the politician who does worst in our head-to-head match-ups against Labour's Jeremy Corbyn
As with the last time the question was asked, David Cameron leads Mr Corbyn by a 2-1 margin when asked who would be the best prime minister. 41% of all voters choose Mr Cameron vs. just 22% selecting Mr Corbyn.
As with Ed Miliband before May's general election, David Cameron is supported by the overwhelming majority of Conservative voters (93%) while support for the Labour leader is much more hesitant (55%).
Jeremy Corbyn continues to trail David Cameron as best prime minister
However, with Mr Cameron having stated his intention to stand down before the next general election, the more interesting figures are how each of his potential successors compare against the Labour leader.
Boris Johnson has an 11 point lead over Mr Corbyn (35% to 24%) but Home Secretary Theresa May and Chancellor George Osborne are effectively tied with the Labour leader.
Other Tory leaders have much smaller leads
