To compound her failure to even make the top 100 with her release, Leanne is understood to have sold a mere 895 copies in her first few days.
The chart flop will prompt many to question the value of winning the BBC One show if it results in so few sales and little chart success.
But the holiday camp entertainer limped to just 134 in the chart yesterday. Coaches from the series Will.i.am, Jessie J and Danny O'Donoghue from The Script all have albums in the top 100, as does Bo Bruce, who was runner-up in the contest last year.

Her poor chart placing comes as last night's knockout stage show drew the lowest figures of the series so far for 'The Voice' with an average of 5.6 million tuning in. Nonetheless, the BBC has ordered a third run of the show for next year.

It was the fastest-selling single of 2012 and the biggest selling 'X Factor' winner so far.
