Credit Suisse First Boston has lost another European credit strategist from its London-based team. Christopher Cloke-Brown left the firm last week, just a few days after Evan Kalimtgis, head of European credit strategy, resigned to join Dresdner Kleinwort Wasserstein, according to officials familiar with the move. A senior CSFB research official would not confirm Cloke-Brown's departure, but said he was actively looking to replace Kalimtgis. Cloke-Brown's destination could not be learned by press time.
