Child tax credits I believe were brought in by New Labour in 1997ish

Family Allownace as it used to be called was brought into play many many years ago

I can see your point - you have no children [ your choice ], so why should people who have them, get credits, yet you argue that case for tax credits, suppose really just got used to having it, then its gone, yes wil be better off with slightly less tax, however £545 worse off per annum due to the CTC going.
