Dresdner Kleinwort Wasserstein (DrKW) has clinched the top spot in the half-year European M&A advisory league table, according to Dealogic.

Jeffrey Rosen, deputy chairman of DrKW, said he believed the acquisition of Wasserstein Perella last year had been important to its ranking. He said: 'Our industry focus and our geographical coverage has been boosted by our new US presence.'
