Ofcom is investigating complaints about Simon Cowell’s decision to let the public vote determine who was eliminated from the latest edition of The X Factor.

A record 16.6 million watched as Welsh teenager Lucie Jones was kicked off the talent show on Sunday night after the public chose twins John and Edward Grimes – nicknamed Jedward – to go through to the next round.

The Irish twins have become firm favourites with the public despite some erratic performances.

The decision to open up the voting has been criticised in some quarters due to the twins’ apparent popularity.

A spokeswoman for broadcasting regulator Ofcom confirmed that complaints had been made, but would not confirm how many had been received – but The Sun reports that a massive 3,000 people have complained to ITV.

She said: “We will assess the complaints against the Broadcasting Code.”

Lucie, 18, found herself in the bottom two with the twins when host Dermot O’Leary announced the results and both acts performed in the sing-off.

When it was his turn to vote for the act he wanted to save, Simon said he would prefer to see the boys again rather than Lucie – but he took the decision to deadlock.

This meant that Lucie, having received the fewest number of public votes, was sent home.
