HE may only be a character in the Beano, but Walter the Softy packs a punch and last week delivered it flush on the stiff upper lip of arch-Brexiteer Jacob Rees-Mogg. Walter, Dennis the Menace's arch nemesis, hit Rees-Mogg with a cease and desist letter, claiming the Somerset Tory MP's distinctive style was ripping him off.

This was immediately followed by a report in the Wall Street Journal, which did not elaborate on the charges, only that they relate to an alleged improper use of company funds. Sorrell categorically denies any misconduct.
