Really?Most people would or should receive about the same on UC tbh. Tax credits could be a nightmare for people on variable income. Tonnes of people ending up in massive debt.
I thought universal credit was a massive flop. complicated and miserly?! Tax credits allowed me to work and get extra to so my wife cold stop work and study. I am not sure UC allows all that. We also had Labours nursery vouchers giving free childcare which allowed me time to work. That was also scrapped by you know who.
