10:10 cropped up in Parliament again yesterday. In her first speech to the House, the first ever Green Party MP, Caroline Lucas, said:

A quick clarification is perhaps needed here. The House itself hasn't explicitly signed up to the 10:10 target – a Lib Dem motion promoting that idea was narrowly defeated last year – but the entire government estate is on board, as well as nearly half of local authorities, plus hundreds of MPs.
