My guess is today's dump would be from 1832 Asset Management out of Canada (They are part of that 48M shares).
In February their declared substantial interest was 30M shares (see notice 2 Feb). On 11 September they advised they were no longer substantial and had sold 5.6M shares so had approx 24.4M remaining. It wouldn't surprise me if they had been trickling them out on market since September and today is the last of them.
