London 2012: Spice Girls Expected to Perform at Olympics Closing Ceremony

But visitors face disruption at U.K. airports as immigration officials plan to strike on the eve of the Summer Games.

LONDON – The Spice Girls are expected to re-unite to perform at the London 2012 Olympics closing ceremony. The possible reunion of the 1990s British pop act is the talk of the town here.

The five singers, Geri Halliwell (Ginger Spice), Emma Bunton(Baby Spice), Melanie Chisholm (Sporty Spice), Melanie Brown (Scary Spice) and Victoria Beckham (Posh Spice) are tipped to join other pop stars such as George Michael, The Who, Take That and Jessie J for the closing show on Aug.12.

Media reports said that one of the two songs the group may perform will be 1996 single "Wannabe," which was a number one hit in more than 30 countries.

Talking on the radio Thursday, Beckham seemed to confirm the Olympics plans. She said that she would "love nothing more" than to sing again with the rest of the group. "I don't know about a comeback tour, but I loved being back with the girls...we are very excited about the Olympics."

But it's not all positive buzz for the Olympics as the countdown to its opening ceremony on July 27 enters its final week.

Immigration officials from the Public and Commercial Services Union are set to strike the day before the opening ceremony. That will mean serious disruption for people jetting into London's airports for the Games.

Senior Conservative members of parliament have accused the union of “holding the country to ransom” as ministers privately questioned the legitimacy of the industrial action. A fifth of the union’s 16,000 members voted, with 57 percent of them in favor of the strike.

Home secretary Theresa May described the action as “shameful” as officials drew up contingency plans to draft in civil servants to man immigration desks.

May told The Daily Telegraph: “They are holding a strike on what is one of the key days for people coming into this country for the Olympic Games. I believe it is not right for them to hold a strike. They will risk damaging people’s enjoyment of coming through into the U.K.”
