Plans for a Spice Girls tour to mark the group’s 20th anniversary has been left in the balance after Melanie C reportedly dropped out of reunion talks.

The Liverpudlian singer – who was hailed as the strongest vocalist during their hey-day – is said to want to concentrate on her own music career rather than perform her band’s old hits.

She follows the lead of Victoria Beckham, who ruled herself out of any more concerts with the Wannabe hitmakers so she can focus on her booming fashion business.

A source tells The Sun: ‘Mel C is out of the reunion for now. She has essentially left the band to focus on a more serious music career.

“She loves the girls but it just didn’t feel right for her to reunite with them at the moment. She has other priorities and obviously it was a bit of a problem that Victoria made it clear she wasn’t going to be part of the reunion.’
