Ann: Appendix 4E and 2017 Annual Report, page-3

I find this slide quite interesting. Posting leaving the company and no longer having a say in the day to day operations, future strategy or having to inform the market of his transactions, TT has been quite busy on the sell side one could say...

I think the majority of / if not all of these sold would of been from March (sub 5c) onwards as TT was technically on the Board and would of had to report any movements to the market.
