The number of ex-Dresdner Kleinwort bankers who have filed against Commerzbank for unpaid bonus payments has now topped 100, after a group of 21 former London-based employees claimed a sum of £16.1m (€17.7m) today.

The group of 21 bankers are seeking a total of £16.1m in bonuses they claim are owed them by the German bank, according to a claim filed today in London's High Court and seen by Financial News. The group is represented by law firm Mishcon de Reya.
