Following close on the resignations of key officials at DECC, the Prime Minister's climate change adviser Ben Moxham has decided to call it a day too.
Ben Moxham, senior policy adviser on energy and the environment at Number 10, has become the latest in a line of key energy experts to leave government.
Moxham is understood to have become frustrated that climate change has slid down the government's agenda.
The Telegraph's Emily Gosden reports that Moxham's replacement is to be Tara Singh, a PR person who used to work at Centrica and before that was a Conservative special adviser.
Wintour's tweet is:
Shake up of no 10 climate change team. Peter Lilley, one of 5 Tory MPs to oppose climate change act, now overseeing energy, but not cc.
Press Association says Lilley has foreign affairs and not energy, according to Josh Garman.
Apparently Tara Singh is currently a spin doctor for Renewables UK.
