I haven't read the article, but I've heard enough on the MSM to establish that, if it is true, it is at least as bad as you say it is. It's criminal behaviour and corruption at its worst. Obviously, in the interests of fairness, I'm want to hear Mone's response. If she cannot put up a cogent defence, then the next question is, what, if anything did the government know, and what did they do to facilitate the criminality that could have been avoided?
Leaving Mone aside, there are times when governments of all colours and nationalities do things where the morality is questionable, and there are other times when governments are in panic mode faced with a situation like a pandemic with which they are unfamiliar and are focused on helping to prevent businesses from going under. That is the time when the system is most vulnerable to abuse, and there's no doubt it was abused.
So getting to the truth of every case of possible fraud is vital. The government must do, and be seen to be doing, that. And since we're likely to have a Labour government in two years time, there is the added safeguard that they will look at incidents of furlough fraud too.
