A major Jewish sponsor of Sydney Theatre Company, property developer Robert Magid, will keep supporting the company provided no evidence emerges that management knew of Saturday’s pro-Palestine protest by three actors.

“It was such an idiotic thing to do, it’s alienated a large part of the audience, but I think the STC probably had no inkling that they were going to do it,” said Magid, whose Pier One Hotel is a season partner of the company.
