We're short of truck drivers, ultimately it's the Government's fault. Press might have shone a light on it, but having seen the supermarkets emptied during COVID it's not like didn't see panic buying as a likely event. They were unprepared for the last two years , then for extra LOLz sat on their hands for a few days until they realised it wasn't going away. Over a week later and the South East is still screwed. Of course it's the Governments fault.
The problem goes way back to relying on forign drivers in the first place. But a big shortage is being caused by the DVLA right now, there are loads of new drivers still waiting for licences to be approved.
