SIR Lindsay Hoyle,

Commons Speaker, has updated the rules of the House to emphasise the need for members’ attire to reflect the seriousness of the setting. ‘It is a privilege to serve as a Member of Parliament and your dress, language and conduct should reflect this,’ he says.

Quite right. However, as that infamous shot of Jacob Rees-Mogg slouching like a well-oiled rake on the green benches in an impeccable Savile Row number proves, the cloth does not always maketh the man. Or manners, for that matter.
