UK prime minster David Cameron has tapped Conservative MP Amber Rudd to serve as the country’s newest Secretary of State for Energy and Climate Change.

Rudd was appointed to her new role on Monday and will succeed current secretary Edward Davey who has held the  post since 2012.

Rudd, 51 , was elected MP for Hastings and Rye in 2010 and served as the parliamentary under secretary of state at the Department of Energy and Climate Change from July 2014 until May 2015.

She has been a vocal supporter of energy efficiency policies and is fond of quoting Margret Thatcher when talking about climate change.

“To those who still say that the Conservatives do not take tackling climate change seriously, let me remind them that it was Margaret Thatcher who was the first ever world leader to sound the alarm on taking action on global warming at the UN in 1989,” Rudd wrote in Business Green earlier this month.
