That works out as:
28 Remain
17 Leave
7 Questionable
Of the ones in the 'Questionable' category: four are journalists/media commentators (from the FT, Wall Street Journal, Buzzfeed and Media Diversified) who didn't express clear views on 'in' or 'out', while the other three (Charles Powell, Christine Ockrent and Ross McEwan of the RBS) should probably be placed in the Remain camp - thus, perhaps, raising it to 30 or 31.
The trend (so far) seems pretty clear, doesn't it?
