As Victoria Starmer left Downing Street, stage left, on Monday morning, you couldn’t help but see the smile on her face as one of relief. Ever since her husband assumed the role of Prime Minister, every outfit she’s put on has been reported on and even highlighted as part of a pay-for access scandal (Labour donor Lord Ali had as it turned out, paid for her Me + Em haul). Walking into that viper’s nest, where you will be painstakingly scrutinised in the hope of finding fault, is an unenviable prospect, no matter how prestigious your new address might be. Mrs Starmer left Downing Street wearing Karen Millen, chastened perhaps by two years of headlines.
