Vaz has been around too long to get into any trouble,
he can buy or sell shares any time, but if it co-incides with a price sensitive announcement then it is of course questionable,
he is aware of this so would not risk anything.
I suppose he could say he had a long standing order in, I would guess because of the timing it is not that market moving.
Hope I am wrong and it sends it to a dollar. (joking here so don't get excited)
