Like I said I read it for 20 years, over the last 2 or 3 it seemed to be getting more left-wing. The Culture section has long been more left-wing than the rest being associated with the arts but that got even more so. TV reviews would often have a left-wing slant as well.
Can you give one single example to establish the truth of that allegation?
If you think the Sunday Times is getting more right-wing you must be in Momentum or something. They're getting more left-wing, try reading it. I did, for 20 years.
sarcasm or drugs?
Those vouchers are a pain TBH Cashiers seem to have problems with them. Aldi don't or didn't even accept them.
