Spoof apology song Nick Clegg Says I'm Sorry has entered the top 150 after the Liberal Democrat leader gave permission to the track's creator, satirical website www.thepoke.co.uk, to release it as a single.
The song only went on sale at iTunes on Friday night, explaining its low ranking, as the chart's other songs have had since last Sunday to climb their way towards the top.
All profits from the song will be given to Sheffield Children's NHS Foundation Trust, of which Mr Clegg's wife Miriam is a patron.
The Script held on to their No.1 slot despite a late challenge from YouTube sensation Psy.
The Script's track, Hall of Fame – which features Black Eyed Peas rapper Will.i.am – is in top slot for a second week, with Example's Say Nothing going straight in at No.2.
Psy's Gangnam Style rose 13 places to land at No.3. Psy is the first South Korean to reach the UK top 10.
