Stop right now, and thank you very much ... yes, it’s Goodbye from the Spice Girls. Forever! Bringing down the curtain on the end of a (very long) era, the ultimate girl power group are calling it a day. Five became four when Victoria ruled herself out of next year’s proposed shows – and now The Spice Girls World Tour 2014 has been axed, once and for all. The decision to retire was reached in a conference call 10 days ago. The quartet agreed that with no Posh in their midst, ticket sales and merchandising would struggle to get off the ground. “Led by Geri, the girls had been plotting a world tour as a four-piece band, culminating in a final night at Wembley Stadium.," says a source. “The three other girls had been initially up for it but once they started having meetings they realised the capital wasn’t there. “They also feared a general apathy from the public if Posh wasn’t in the fray, leading to dates not selling out. “Victoria’s obviously a big pull when it comes to the fans and she also guarantees press coverage.” In fact, it’s not been a good few days for the Spices generally. Last week it emerged the girls’ West End show Viva Forever! wasn’t, well, for ever . The flop musical, written by Jennifer Saunders, closes next month despite heavy investment and a fanfare of pre-publicity.
