The enigmatic Regal Encore triggered a totescoop6 rollover at Ascot this afternoon after he knocked out the 48 tickets still chasing the prize in the fifth leg at odds of 20/1.

The earlier damage had been done by Gino Trail (13/2), Poker School (8/1), Unowhatimeanharry (6/5F) and Yala Enki (3/1F) to send a win pool of £302,483 rolling over to Boxing Day.

The bonus fund was not in play and will kick off with £74,629 in the kitty when the pools reopen after Christmas.

totepool spokesman Andrew Griffiths said: “Regal Encore was a showstopper for all the wrong reasons at Ascot but a potential £500,000 Scoop6 could really get the party started on Boxing Day.”

A total of £145,938 was invested into this afternoon’s pools and there were 160 winners of the £159.60 place dividend.
