It's a practical question I have. Because of the contiguous nature of the very highly ambitious development plans for housing along the M4, north of Cardiff and westwards, from northern Cardiff in the South Wales Central region, through the neighbouring southern parts of Pontypridd, onto northern Bridgend, there's a heightened imperative to make sure that all the local authorities are talking together, working together, developing their plans together to avoid the situation where a laudable set of ambitious aims in one area leads to the detriment of the laudable aims within another. So, unless there is co-ordination of plans, what we could end up with not only from local authorities, but transport authorities as well, is gridlock rather than releasing the economic potential. Now, the leaders of Rhondda Cynon Taf and Bridgend Country Borough Council are already working together to plan their way through this, but can I ask the First Minister—and, by the way, welcome him to his first First Minister's questions as well—what strategic hand can the Welsh Government play in ensuring that the transport infrastructure is definitely in place to enable the grand plans for new housing to end in hundreds and hundreds of happy home owners not grumpy, gridlocked constituents?
