Tehran, April 25, IRNA -- Iran's Majlis (Parliament) on Sunday approved double urgency of a bill to postpone by-election in Tehran constituency and instead hold it concurrently with the next presidential election.

Parliament by-election is expected to be held on May 7. So far, out of 30 seats for the seventh Majlis in Tehran, Rey, Shemiranat and Eslamshahr constituency, 29 MPs have received enough votes and one candidate will be selected in the second round of elections.

The bill was signed by 18 MPs to add one paragraph to the Article 9 of the Election Law during Majlis's Sunday session.

The signatories believe due to the vastness of Tehran constituency and selection of only one MP on May 7, holding the second round of election would impose heavy expenses on the country.
