U.K. Stocks Drop On Potential Spanish Debt Downgrade

European markets were modestly weaker overnight after Moody's put Spain's Aa1 rating on review for a potential downgrade. “Jumpy investors will not be pleased at the return of euro-zone fiscal difficulties to headlines, and it remains to be seen whether this news will cut short the Santa rally,” Ben Critchley sales trader at IG Index said. Banks with potential Spanish debt exposure like Barlcays BCS, Lloyds Banking Group PLC LYG fell around 1%.
