On FTSE shares orders can be placed by PIs with DMA directly on to the LSE orderbook. Those orders can then be part filled, bit by bit, which can sometimes leave you with a very small number of shares left over. If you're quick you can then cancel you'r order and keep those leftover shares if you want, or if you leave them they will eventually be picked up to part fill someone else's order. Its just the way it goes. So that 1 share might have been part of a bigger holding that just got left on its own the way the transactions went. The PI won't have had to pay a full commission to sell it or buy it though. With DMA there's usually one larger commission fee for the whole order in its entirety, plus a smaller fee for each part of the order as its filled.
