Britney Spears' upcoming concert in Tel Aviv has forced Israel's Labor Party to defer its leadership vote by a day.

The problem is more a technical one than concerns about a mass defection to the outdoor concert on July 3 by the pop star: both events were scheduled for the same day in north Tel Aviv (Hayarkon Park for Spears; the adjacent Convention Center for Labor).

One problem Labor would face is hiring enough stewards and security guards for its primary vote, as many would be otherwise employed securing the concert, a senior party source explained.

Spears is scheduled to perform on July 3, according to her representatives, as part of her Asia tour.

The precise location of the primary voting booths has yet to be released. However, party sources assume that, as usual, at least some will be in the Convention Center, where the counting also takes place – opposite the site where Spears is set to perform.

However, the source did admit to some consideration for the party faithful who want to vote in the primary and then watch Britney do her thing – especially as major traffic routes around the Convention Center will be blocked to traffic for security reasons.
