I thank the right hon. Lady for her warm comments about the birth of our daughter. May I report to the House that mother and baby are doing well? It is nice to come back to Parliament for a rest.

When I made those comments, I was not talking about my ministerial colleagues; I was talking about some voices on the Conservative Benches, particularly in the other place, who question the science of climate change, and I think that is very unhelpful. The right hon. Lady talks about a decarbonisation target, but it was this Government who brought forward legislation on a decarbonisation target. The Labour party did not have one in its manifesto and neither did the Green party. We took the policy forward and it is in the Energy Act 2013.
