12:13 Miss Anne McIntosh (Thirsk and Malton) (Con)
May I join the hon. Member for Wrexham (Ian Lucas) in his bid? May I also commend the Foreign Secretary for placing so much emphasis on climate change? Will he use the next CHOGM to progress the matter so that we can carry the agenda forward in continents such as Africa that are battling with famine now but previously with drought?

Mr Hague
Yes. Climate change is an enormously important subject for the Commonwealth, which is a remarkable network now encompassing almost a third of the world’s population across many different continents and climatic zones, so I hope that climate change will continue to be discussed in many different Commonwealth forums and that we can use our membership to promote the legally binding global deal on combating climate change. That is what we need.
