“I’m looking forward to welcoming Matthew Hancock and Amber Rudd to DECC. They join us as we are increasingly demonstrating the success of our policies to meet Britain’s energy and climate change challenge. I know their combined experience and abilities will be an enormous asset as we complete this Government’s work.

“I want to thank Michael Fallon and Greg Barker for their immense contributions to turning around the legacy of energy underinvestment we inherited. I was particularly grateful to Greg for his support on my battles on climate and to Michael, for his backing for my pro-competition approach to the Big Six.”
