So the share consolidation I believe was 14 old shares will give you 13 new shares and the special dividend. So your original 98 ÷ 14 = 7 then × 13 = 91. Theoretocally the special dividend would allow you to make up any consolidated shares. You should have received just short of £20 in dividends today which would allow you to buy back the 7 shares (dependant on todays prices). I believe they have basically reduced the number of shares available, so after the dividend you can own slightly more of the company.
