izaki,florry, will not tolerate this guy for too long and they will spreads some news themselves soon.
They will let these so called tracker funds sell.
and izaki/florry's friends will buy up £10 -20 down .and the price will come back.
ps , the trading spread has been the closest for a very , very long time. mm's are nervous as well. if they try to short, then they could get stuck to if tracker funds don't sell.
pps. this happened to florrys broker they shorted qxl's shares only to get burn't when the selling sidn't happen.< they lost a lot of money and of course some reputation.
