Zaoui & Co, the Mayfair advisory boutique fronted by dealmaking brothers Michael and Yoël Zaoui, returned to profit in the UK last year thanks to a rebound in European mergers and acquisitions.

According to accounts filed with UK Companies House on Thursday, Zaoui & Co reported net profits of £5.3m for 2017, recovering from a loss of almost £1.3m a year prior. This was fuelled by a 247% surge in revenues to £12.5m.
