Exclusive:   * Sir Keir Starmer and Rachel Reeves plan to blame Nigel Farage for tax rises in the Budget. They will say he delivered Brexit with 'easy sloganeering' then walked away, failing to take responsibility   * They will explicitly link the OBR's upcoming productivity downgrade - which has left a huge hole in the public finances - to the economic hit after Brexit. Rather than just blaming the Tories they plan to go for Farage personally   * So much for the conference afterglow: A new analysis of polls show just how dire things really are for Labour and the Tories   * Starmer is the most unpopular PM on record, while Labour suffered the greatest fall in popularity of any governing party in their first 10 months   * The task facing Kemi Badenoch is huge.

The Tories best hope is that migration reduces in salience as an issue by the time of the next election thetimes.com/article/8875501…
