Going into the second round of voting in the Conservative leadership contest – on Tuesday  – Boris Johnson’s place on the final ballot is all but secured, and the remaining four are fighting it out in increasingly desperate terms.

To make it through the second round each contender needs 33 votes from their fellow MPs. If all make that threshold the candidate with the lowest number of votes will be kicked out of the race. One candidate will be kicked out each day (unless more than one fail to meet the threshold), until there are two left. As it stands, the membership – who make the final call – will be choosing the next Tory leader between Boris Johnson and another.
