Their fourth studio record is on course for the top spot after shifting an incredible 43,000 copies in a single day.
The mammoth sales are even more impressive considering Olly Murs sold 58,000 in seven days to land his fourth No.1 on Friday and Robbie Williams sold 67,000 the week before.

US heavy metal gods Metallica are about 10,000 copies behind them at No.2.
