Robey Warshaw, the investment banking boutique that advises on some of the top UK deals, has paid its senior dealmakers £26.4m as former UK chancellor George Osborne was included in the top ranks for the first time.

The boutique, which has carved out a role as a key adviser to FTSE 100 firms despite having just 13 staff, paid out £26.4m to its four partners in the year ending 31 March 2022, according to newly-published accounts on Companies House.
