Rangers supporters have reacted with anger after an iPhone personal assistant service claimed the club is just four years old.

The voice-operated computer program, which can answers questions and provide recommendations for the user, has provoked outrage among some Rangers fans who quizzed it on the origins of the Ibrox club.

Users have discovered if you ask the voice-activated program to tell you when Rangers were founded, it responds with 2012.

Rangers were formed in 1872, but fans of other clubs have claimed that when the club went into liquidation in 2012, they ceased to exist.

It took little time for Celtic fans to taunt their rivals about the iPhone response but Rangers fans insisted there “always has been and will always be a Rangers”.

Apple declined to comment but a source close to the firm insisted it was “not a deliberate attempt to mislead”.
