Two longtime Goldman Sachs partners have reportedly threatened to quit after they were passed over for a position on a top committee established under CEO David Solomon.

Mark Sorrell, who co-heads mergers and acquisitions in the firm’s London office, and Gonzalo Garcia, who co-heads the European investment banking division, have indicated they may resign after they were left off a new committee formed in the global banking and markets unit, according to Financial Times.

The two were left off even as co-heads who work alongside both men — Stephan Feldgoise in mergers and acquisitions and Anthony Gutman in European investment banking — were included in the dozen-member committee, FT reported.
