Numis, the city broker led by Oliver Hemsley, has parted company with it's chief finance and operating officer after just four months.
A spokesman for Numis confirmed that Justin Van Wijngaarden, who was headhunted from rival Jefferies last September, left the firm in January.
The circumstances of his surprise departure are unknown. Mr Van Wijngaarden, who was chief finance and operating officer for Jefferies & Company International for more than two years, was unavailable for comment.
Prior to Jefferies, Mr Van Wijngaarden spent nearly 10 years at Lehman Brothers.
News of his exit comes at a tricky time for Numis. The broker was hit in August by the departure of Amanda Shields, the firm's compliance officer. Reports suggested that Ms Shields was considering legal action over her exit, although it is not known whether a case was pursued.
Numis revealed in December that it had slumped to a pre-tax loss of more than £10m during the year, down from a profit of £16m in 2008. However, the company has enjoyed a strong start to 2010, advising on a number of deals including the £418m float of Hugh Osmond's acquisition vehicle, Horizon.Reuse content
