Vice President for Executive Affairs Mohammad Shariatmadari is to attend the inauguration ceremony of the next Afghan president on behalf of the Iranian government.
President Hassan Rouhani had hailed formation of a national unity government in Afghanistan as the basis to further strengthen security and stability in the country.
Ashraf Ghani will be sworn in as Afghanistan's president today in the presidential palace in Kabul under a power-sharing deal signed with his rival Abdullah Abdullah last week. Some 200 dignitaries and officials from around the world have been invited for the ceremony.
The power-sharing agreement ended almost six months of tension following disputed presidential elections, in which both sides had accused the other of fraud. Under the deal Ashraf Ghani becomes president while runner-up Abdullah Abdullah will nominate someone to a post similar to that of prime minister. Ghani served under outgoing President Hamid Karzai as finance minister. He also ran in the 2009 presidential election, in which he just won three percent of the vote.
