Ali Akbar Velayati made the remarks during a speech at a ceremony marking the 34th anniversary of the victory of the Islamic Revolution in the Iranian city of Qom.
He added that it would be a big problem if the Principlists do not win the upcoming presidential election.
Velayati also pointed out that three of the potential candidates of the Principlist camp have decided that only one of them will declare candidacy, noting that there may be also a fourth person not affiliated with the coalition who might also win votes.
The Iranian official further stated that the upcoming election will have major differences with the past ones as the country is in critical situation in relation to the regional issues.
Iran's Interior Minister Mostafa Mohammad-Najjar announced on December 15, 2012, that the Islamic Republic’s eleventh presidential election will be held on June 14, 2013.
He added that the registration of presidential candidates will be conducted from May 7 to May 11, 2013.
The president of Iran is elected for a four-year term in a national election. Candidates for the presidency must be vetted for qualifications by the Guardian Council.
