Welsh Government is really keen to support the idea of the Swansea bay metro, which I think is something that the Member is particularly interested in, in terms of how it can provide a more integrated response to the transport needs of people living in the Swansea bay and wider areas. So, Welsh Government has provided some funding to undertake a scoping exercise to see what would be possible. Obviously, that's a longer term vision for the area, so we need to be looking to see what we could do in the more immediate term in terms of supporting our bus services, for example. So, there's quite exciting work that I know Ken Skates is keen to take forward in terms of improving the power of local authorities in terms of bus services, to ensure that the services in those areas are better able to respond to the needs of local people. But we're very much alive to the importance of public transport, not least because of the pollution incidents that we do see in our particular part of the world as well.
