At a shadow cabinet briefing David Lammy asked Michael Marmot, a health inequality expert, how Labour should communicate to voters the terrible impact of worsening poverty over 11 Tory years. Marmot answered it should tell the truth about serious problems and be bold on how to fix them. Comrades around the party’s top table whisper the shadow justice secretary’s own intentions will reveal whether he believes Labour can win a general election to solve the issues. The next London mayoral election is May 2024, six months before Boris Johnson must go to the country. Should Sadiq Khan pull back from a third run, my snout says, a Tottenham MP who lost out to him in 2016 fancies his chances. A capital job for Lammy would be evidence of Labour’s national woes.
