When it comes to matters of political timing, Rishi Sunak has had a bit of a problem this week.
It started with a leak to the BBC that he was planning to reverse government policy on a range of climate change commitments, reportedly a matter of intense private discussions at No. 10 in recent weeks.
At a hastily convened midweek press conference, Sunak stoutly denied the change of policy had anything to do with a by-election victory that was attributed by many to his party’s opposition of a clean air zone. Denying the connection was cue for hollow laughter, with the need to rescue his party in next year’s general election obviously the real motive.
