A furious email arrives from David Buik, the BGC Partners commentator who one might just describe as a conservative. He is enraged about the damage caused by rioting students to Millbank Tower. “The Tower is actually owned by the Reuben Brothers,” Buik says, before listing their impressive record of charitable donations. “Neither went to university,” Buik says, just to underline where his sympathies on this issue lie. Let’s hope they have some decent insurance.
