The Spice Girls are to make an announcement about their future plans next week, sparking speculation that one of the world's most successful girl bands is set to reunite for a new album and concert tour.

The Spice Girls sold more than 30 million albums and topped charts around the world before Posh, Scary, Sporty, Baby and Ginger decided to pursue solo careers with differing levels of success.

Geri 'Ginger Spice' Halliwell left the group in 1998 and the other four quit in 2001.

'The Spice Girls are set to make an official announcement to the world regarding future plans on Thursday 28th June,' their management said in a statement.

'No further information can be given at this time but given the band's unique history you can be sure to expect the unexpected,' Simon Fuller's 19 Entertainment said.Reuters
