I thank the Cabinet Secretary—I'm not sure what she is when she does this, leader of the house or Cabinet Secretary, but she's a member of the Cabinet, anyway. Thank you for that reply. I really struggle to understand how we can actually move on many parts of rural Wales to the automated future, the robotics future that we've been talking about in Welsh public life only today if we don't have a viable and reliable mobile phone signal. You can't do your automated farm, for example, if you don't have that. You can't have automated cars if you don't have that. We can't have developments, even if we do see a new train line between Carmarthen and Aberystwyth, without a reliable mobile phone signal for the track engineering and everything else.

You say you don't actually know the availability of this, and I understand it's not devolved, but there are ways of plugging the gap. The Scottish Government has a 4G infill programme. It has looked at changing planning regulations, trying to do the best it can about mast sharing, forcing companies to work together and, indeed, some public Government investment in filling in the notspots. Is that something that the Welsh Government is considering, and could we see a 4G/5G national programme, similar to the broadband programme that you've been rolling out over the last couple of years? I'm sure your postbag deserves a few extra letters on these matters as well.
