Well, I'm afraid the verb 'compel' doesn't describe the position that we are in, but what we are certainly in a position to do is to go on making the case whenever we have the opportunity to do so. And our case for electrification doesn't stop with the south Wales main line either, Llywydd; the north-Wales coast line needs to be electrified as well, so that the services can be run between north Wales, northern England and then on to London. We need rail infrastructure to be devolved, we need a fair funding settlement with it, and then we will be able to prioritise and deliver the decarbonisation of rail services, not just in the core Valley lines, which we are already doing, but on those other parts of the system as well.
