on 23 May, responding to comments made by future Speaker John Bercow. In Tony Blair's frontbench reshuffle in May 2006, he was made Minister for the Third Sector, with responsibility for voluntary and charity organisations. Cabinet On 28 June 2007, the day after Gordon Brown became Prime Minister, Miliband was sworn of the Privy Council and appointed Minister for the Cabinet Office and Chancellor of the Duchy of Lancaster, being promoted to the cabinet. This meant that he and his brother, Foreign Secretary David Miliband, became the first brothers to serve in a British cabinet since Edward and Oliver Stanley in 1938. He was additionally given the task of drafting Labour's manifesto for the 2010 general election.

This, a government source told the Guardian, effectively represented "a complete rewrite of UK energy policy for the future". Miliband represented the UK at the 2009 Copenhagen Summit, from which emerged a global commitment to provide an additional US$10 billion a year to fight the effects of climate change, with an additional $100 billion a year provided by 2020. The conference was not able to achieve a legally binding agreement. Miliband accused China of deliberately foiling attempts at a binding agreement; China explicitly denied this, accusing British politicians of engaging in a "political
