LONDON, April 28 (Reuters) - Europe's bank shares sank on Friday, heading for their heaviest daily loss since March 23.
An index of euro zone banks was last down 3%, and a wider index of European banks was down 2.5%, underperforming the pan-regional STOXX 600 index, which fell 0.4%.
The biggest laggards in percentage terms were UK lender Natwest, which fell nearly 6% after reporting large outflows in the first quarter, Banco Sabadell, which dropped 5.7%. Its results on Thursday beat expectations but also contained evidence of a slide in customer deposits in the first three months of the year. (Reporting by Lucy Raitano; Editing by Amanda Cooper)
