Iran's constitutional watchdog, the hard-line Guardians Council, has reversed a ban on 1,500 candidates who had registered to run in the February 26 parliamentary elections.
Iranian state media said the new list of approved candidates -- now numbering over 6,200 -- had been sent to the Interior Ministry.
Last month, the Guardians Council, a vetting body made up of clerics and jurists, disqualified thousands of moderate and reformist parliamentary candidates and four-fifths of the candidates for the body that will choose Iran's next supreme leader.
That decision sparked a growing dispute between Iran’s hard-liner and reformist factions.
It is unclear how many of the newly approved candidates are considered to be reformists.
The upcoming vote is seen as a showdown between hard-liners and moderates, who hope for a boost in the wake of the newly implemented nuclear deal with world powers and the lifting of international sanctions.
