I personlly think the backtracking is the worst part? If they had been open about it from the start, that they think the current levels are too high, then it would still have been typical Tory thinking BUT at least honest. The fact that he he said - and said straight up, not in an ambiguous way - that this in-work money would be safe from cuts and then has just blatantly and immediately reduced them... it's insane. There's having scummy policies, there's twisting things in a dishonest fashion... that always goes on in all parties... but a straight up bare-faced lie? "Vote for me, I will NOT do this. Thanks for voting teehee actually I'm going to do it

"
AND it's not like this is two or three years down the line when maybe it could be argued that old promises have to be looked at because of changing circumstances. IMO, this must have been part of the plans already in the works before the 2015 election campaign even started.
