Okay I guess you haven't heard anything about it, basically, they're planning to blow 50 billion pounds on doing something that was being done already by the private sector (and was specifically given to the private sector to do instead of it being state owned), but it gets better. Once it's done they're going to give it away for free, putting tens of thousands out of work, devaluing millions of peoples pensions, and they have absolutely no idea how they're going to pay for it.
So yeah that's why their free fibre policy has made them a laughing stock, and the most annoying thing for Labour voters like myself is that it's not even an unavoidable gaff, all they had to do was talk to one expert and they would have been told it's a terrible plan, it won't work and they don't understand what they're talking about. But noooo they don't do that and instead they send McDonnell and Abbot on the radio to talk it up, despite they fact neither of them know what broadband is, how it works, what the current system is, what their plan will en-tale or even that you can get an internet connection over 4G/5G.
End result they both end up looking like halfwits and the whole thing reflects so badly on the labour party that it overshadows what a terrible week the Torys have had
It's called diplomatic immunity, look it up.
