He also asked what was the status of grants to biotech start-up BioDiscovery since its decision to relocate its global R&D centre to California, and why a grant was made to the unprofitable local unit of Bayer, the Germany conglomerate "making huge profits".
"I support the concept of Callaghan and I want it to work," Cunliffe said. "But the quality of some of its grant making, lack of clarity on some of its criteria and policy failure that grants are automatic if applications meet the criteria have led to some bizarre results."
Suckling said that applications "are carefully scrutinised".
"There will be failures."
Chief financial officer Perry said of those grants singled out for criticism, not all the funds had been paid out. Clawback provisions gave Callaghan scope to recover grants. In the case of BioDiscovery, it had elected not to seek its funding. No money had been paid out to Chatham Rock. In its 2014 annual report it cites grants of almost $270 million made last year to 541 businesses.
Mary Quin said: "With entrepreneurs, you can have people who've had one, two, three or four failures. Looking at failure as a negative can be a mistake."
