There is a growing feeling of inevitability about the burgeoning success of Nigel Farage and Reform UK. Last week, Farage revealed ex-Tory minister Dame Andrea Jenkyns as the latest Conservative defector to Reform; this week it was Tim Montgomerie, party activist for 33 years, founder of ConservativeHome and adviser to Boris Johnson during his premiership. At this rate, few eyebrows would be raised if next week saw Kemi Badenoch cross the aisle.
