Method

The pledge-card format, with a named senior figure promising specific policies, was now the page's main tool, each card past a million impressions. Two new long-running lines started: the face-coverings petition and the "Uniparty" card, which frames Labour and the Conservatives as one bloc.

Method

The by-election campaign was built around the party leader's profile ("That is the power of the Leader of the Green Party") and local endorsements. One ad passed a million impressions, a large reach for a single constituency. A national housing video had the most spend (£6K–£7K).

A full-length clip of Badenoch challenging Burnham at his first Commons appearance as Prime Minister after the summer recess ran alongside petitions on serious offenders' sentences, approving the Jackdaw gas field ("45,000 have already backed our campaign") and scrapping the holiday tax. There was also a local video on Wandsworth council finances.

What changed

What this week tells us

  • On the national pages, the Greens advertised their leader's by-election far more heavily than Labour did its defence of the seat.
  • Reform's "Uniparty" card started on 15 September and was still running in late October.
  • As Parliament returned, the Conservatives' lead video was a direct Badenoch-versus-Burnham contrast.
