Iran admits vote 'irregularities'

The Iranian election supervising body, the Guardian Council, has acknowledged irregularities in more than 50 constituencies in the disputed presidential election.

It said that the number of votes collected in 50 cities had surpassed the number of voters registered, but added that it did not affect the overall result of the election won by President Ahmadinejad.

Teheran remains in a high state of tension.
