I wouldn't call it "institutional support" for todays placement.
More likely sophisticated clients of RBS Morgans.
I note the TH came on Thursday, one day after the RI went EX, however the "offerees" still got the entitlement for the RI.
At 21c, their av entry if they take up the RI is 21+18 / 2 = 19.5cps
