Suella Braverman criticised by Labour over ‘deeply divisive’ migration speech – as it happened

Home secretary argued that uncontrolled' migration poses existential challenge for institutions of the west'

The Sun is carrying a story today saying Rishi Sunak's decision to stall the net zero ban on selling new petrol cars has seen him catch up eight points in the polls". It is based on the results of this Deltapoll poll.

For a more considered view, it is worth reading this article in the i by Prof Sir John Curtice, Britain's leading psephologist. He says the impact of the net zero speech on the polls has been much more modest. Here is his conclusion.

Whatever the popularity of the measures, if, as has been alleged, Mr Sunak's motivation was to try to reduce Labour's lead, it looks as though he has so far reaped little reward. Four polls of voting intention conducted after last Wednesday's announcement have so far been published. Between them they put Labour's lead on 17 points - just a point below the polling average shortly before last week's drama.

Moving the polls is, it seems, just as difficult as dealing with climate change.
