William Hill bookmakers have the barn owl as second favourite behind the robin to take the win.
Bookmakers, already week after last week's budget raised the tax on lucrative fixed odds betting machines from 20% to 25%, dipped again on reports that the weekend's Premier League football fixtures were bad news, with all the favourites winning and costing them £20m.

Several bookmakers also took the opportunity to shorten their price against Golden Horn, the favourite, although John Gosden's colt moved in the opposite direction with William Hill, out to 15-8 from 7-4.
