Who's backing who? How Tory MPs line up behind the candidates

Apart from the hard-core campaigners, who have declared their support for each of the six Conservative leadership candidates, there are unofficial lists of potential supporters collected by each camp. The Independent has identified more than 100 Conservative MPs from those lists, and while some might be mistaken - particularly with MPs wanting to consult their local parties before casting their votes on 10 June - they could provide a rough indication of the way in which the first-round voting might be weighted.
