Your political coverage this week has been insightful and informative. But in your article on the probabilities of success for likely contenders for the Tory leadership (Who will replace Boris Johnson? The runners and riders, 7 July), their “chances out of 10” add up to 46, a statistical impossibility. With such a long list of names, a recalibration is required, giving chances out of 100. On that basis, Ben Wallace, Rishi Sunak and Penny Mordaunt would score 13/100, with Priti Patel trailing at 4/100 – a fair summary of their competencies.

• Your editorial (7 July) refers to Boris Johnson as “the worst prime minister in modern British history”. Why the qualification? Has there ever been a worse one in our history?
