According to The Mirror, the second single from the X Factor winner's debut album has been omitted from commercial radio stations owned by Global, including Heart, Capital FM and Galaxy.
Fans of McElderry have accused the company of leaving 'Ambitions' off the stations in order to boost sales of The Wanted's album, which is released on the same date as McElderry's forthcoming LP.
The newspaper reports that The Wanted are represented by Global Talent - who are owned by the same company as Global Radio - which has sparked criticism from McElderry supporters.
One fan tweeted: "Why have Global Radio played @theWantedmusic,managed by Global,2148 times in last 30 days but played @joemcelderry91 0 times? (sic)"
Global Radio's official spokesperson declined to comment. However, a source apparently said that Global's decision was made because officials at the station did not like McElderry's new track.
