The release of a video game hailed as the biggest in Sony PlayStation's history has been delayed amid fears that some background music could offend Muslims, it was revealed today.

LittleBigPlanet's release date was put back after it was discovered that one of the background music tracks to the game included expressions from the Koran.

It was reported that the game would be re-programmed without the offending song, a track by Mali-born singer Toumani Diabate.

A statement on the LittleBigPlanet website said: "We're sure that most of you have heard by now that one of the background music tracks that was licensed from a record label for use in the game contains two expressions that can be found in the Koran.

"We have taken immediate action to rectify this and we sincerely apologise for any offence this may have caused.

"We will begin shipping LittleBigPlanet to retail in North America the week of October 27."

The British-created game features a rag doll hero called Sackboy. Players can customise the toy and then control it to run and jump through a world designed to appeal to all ages.

The concept was developed by games designer Media Molecule, based in Guildford, Surrey, and allows players to design their own level in detail and share it with friends over the internet.

A statement on Media Molecule's website said they were "shell-shocked and gutted" by the delay.

"We learnt... that there is a lyric in one of the licensed tracks which some people may find offensive, and which slipped through the usual screening processes," it said.

"Obviously MM and Sony together took this very seriously. LBP should be enjoyable by all."
