Tell you the bit that confused me most...
Correct me if I'm wrong, but the current threshold for paying any tax was already £10k, right? So... they've announced proundly that "no one working 30 hours per week or less on minimum wage will pay any income tax".
Now... if my maths is right... and it usually is... 30 (hours per week) x £6.50 (min wage) x 52 (weeks in the year) = £10140. SO what they have announced is that you won't be paying 20% tax on £140 a year. 20% x 140 / 12 (months) = ... £2.33
That's right folks. Low earners will be £2.33 a month better off! Yeee-eee-eeaaah, there's a party in the UUU-K.
I suppose maybe they're just promising that the threshold will increase in line with the minimum wage?

As for the rest of it... meh? It's largely meaningless. Whether or not any of it will happen, and anything else that might happen, is really pot luck. All talk.
