From the article:
"We would need a huge influx of immigrant labour to do this. I'm not clear why such labour would come to the UK given our currency and political climate and, of course, the rest of the world wants such people too."
Well that's BS. We need labour. The labour could be immigrant or it could be domestic. From the rest of his sentence he's simply trying to fit a political rant into a space it doesn't belong.
"It isn't impossible but it requires basically [a] hoarding of optical fibre, which means paying more than everyone else; massive hoarding of labour, which means paying more than everyone else; [and] an unprecedented degree of tolerance of roadworks and transport disruption."
Or, for example, we could understand that increasing demand will increase supply, thus no need for hoarding of anything, especially physical goods. He's fallen for the socialist lump of labour fallacy. We could avoid the road works by running the fibre under the footpath. When all you want to achieve is problems, all you'll get are problems... however, if you want to achieve success....
Solving the problem might not be easy, it might even be bloody hard work, but this fool seems to have given up before ever trying to find a solution.
was famously behind the purchase of an unusable water cannon for the police, later sold for scrap at a £300,000 loss.
Firstly, he can't be responsible for the price his successor achieved when disposing of the cannons. Given the different colour rosette, there was every incentive to get the lowest price possible.
What Khan has achieved though, is again leaving literally zero enforcement at scale between bobbies with truncheons, and soldiers with lethal rounds. TASER doesn't scale up for crowds, and doesn't claim to do so. Next time there's a repeat of labours london riots, when Blair was only a few hours away from deploying the military because the police had lost all control, those water cannon are going to look like a good option; which is how they came to look like a good option last time. Personally, I'd rather we had as many options as possible between "hit with a stick" and "shot in the face", because all they really do is reduce or delay the "shot in the face" part.
