PARIS, May 22 (Reuters) - Cross-border mergers between European banks are structurally unlikely, Societe Generale CEO Slawomir Krupa said on Wednesday.

"In Europe today, they are extraordinarily unlikely for a number of reasons, the first of which is regulatory: there are significant capital surcharges linked to the size of banking institutions," he told shareholders at the company's annual general meeting in Paris.
