This is absolute rookie stuff. There is just absolutely no way that a headline like this should ever make the BBC News website.
It being the weekend is no excuse, either: political news *always* drops on Saturday night, for the Sunday papers.
This would be a bad headline even with the "£50bn in savings" referred to as a claim and "overhaul welfare" in quotes – because no one credible thinks there's even close to that in savings to be found. But stating it as plain fact is just dire.
The BBC has a very tough job as the national broadcaster and lots of what it does involves difficult balancing acts.
But this isn't one of those situations. This is just amateur hour.
