The argument is made by some that MPs working in second jobs is a good thing because such professional expertise enriches parliament (Geoffrey Cox missed winter fuel votes while working abroad in second job, 11 October). There is a simple solution. When I was a clinical professor at a UK university, I was allowed to engage in private practice on the condition that I donated all such earnings to my principal employer (the university). I suggest Geoffrey Cox does likewise.

• Joy Webb misses the point when she complains about food waste at Halloween (Letters, 11 October). In order to be used as a decoration, a pumpkin has to be hollowed out. We can’t be the only people eating delicious orangey soups and pies after a hard night’s trick or treating.
