The appointment of Greg Clark as a new Business, Energy and Industrial Strategy Secretary spells the end for a department which put climate change at the top of the agenda.
Just eight years after it was created by then prime minister Gordon Brown, the Department of Energy and Climate Change (Decc) is being merged into Mr Clark's new department and losing the "climate change" part of its name.

The US president has welcomed the Paris climate change agreement, saying it demonstrated "what's possible when the world stands as one".
Barack Obama emphasised the US role in the developments that led up to the Paris agreement, including the US role in the earlier 2009 Copenhagen talks, but said the Paris agreement had only been achieved because nations came together.
"Today the American people can be proud because this historic agreement is a tribute to American leadership. Over the past seven years, we've transformed the United States into the global leader in fighting climate change," Obama said.
He said the agreement was not perfect, but that it "establishes the enduring framework" to solve the climate crisis.
