LONDON (AP) — Two leading credit rating agencies took steps Thursday toward downgrading Barclays in the wake of a trading scandal that’s seen three senior Barclays executives, including CEO Bob Diamond, hand in their resignations.

Although both Moody’s and Standard & Poor’s maintained their ratings on the bank, they lowered their outlooks to “negative” from “stable.” That means that a downgrade of the actual rating is now more likely.
