Credit Suisse, Hoare Govett and UBS have boosted their mid-cap broking client rosters, while Citigroup and JP Morgan Cazenove have lost out, following the FTSE Group's quarterly review of its indices and other broking changes.

Credit Suisse has gained a FTSE 250 client after BlueBay Asset Management, the UK specialist credit asset manager that floated just four months ago, was elevated to the mid-cap index to replace financial administration company PayPoint.
