Supreme court has ruled in favour of the banks regarding car finance compensation (over commission). They however, ruled in favour of one customer who incurred the highest (commission?) charges, and it must be repaid in full including with interest (the overcharging part).
So lenders will breath a sigh relief as this will cost them something like £20B (this figure still seems high, so maybe not correct) instead of what could have been £44B - the decision was purposely held until todays markets closed, as not to cause an adverse reaction, and to give the markets time to think about the ruling.
Treasury also breathing a sigh of relief, who originall rejected these claims, due to the effect it would have on our economy, but the Supreme court does not rule from that angle, it only rules on the application of UK law (so it says).
I think the financal sector were worried they were looking at another big PIP level of payouts again. All of this is off the top of my head, so hopefully I've understood it correctly.
Edit: Just found a link, but doubt this will include financial numbers...
