Agreed. Hard to see what else they could do. Incredible support for jobs. Totally unprecedented, and this from the Tories. I doubt Labour would have done more.
You 100% don't know what Labour would have done so that's pure speculation.
But I wouldn't expect Starmer to oppose much. He's certainly not going to go against furlough extension or anything that is commonly accepted as economic stimulus. It would be suicide.
Much as with vaccines, Labour not opposing isn't Starmer being weak, it's the government doing well. I thought the Boris backers would be loving that rather than coming out with yet more cheap digs about Labour,
