Well, I thank John Griffiths for that. I completely agree with him, but of course we have to take actions to support any declaration and the transport field is certainly one where carbon emissions and the transition to a low-carbon economy has to take place, and the south Wales metro is key to our ambitions in this part of our country. John Griffiths will know that the White Paper, 'Improving public transport', has integrated transport at the very heart of it, encouraging people to walk more and cycle more, but also to look at the way in which bus transportation, which after all carries far more people every day than trains do—that we make bus travel a public service responsibility again. Because, when planning bus services is properly back in public hands, then we will be able to carry out the sort of integration of public transport that John Griffiths referred to in his question, and it's exactly that approach that the Minister intends to set out in the new Wales transport strategy, which is promised for later this year.
