Hashimi has denied the charges he says were fabricated by Maliki's government, and said he was willing to face judges in the northern Kurdish enclave, which has its own regional government and armed forces. The crisis risks unravelling a fragile year-old power-sharing deal among Shia, Sunni and Kurdish blocs that have struggled to overcome tensions since sectarian slaughter in the years after Saddam Hussein's fall in 2003.
Shia leaders say the case involves law enforcement against individuals and does not target a community, but the Sunni minority fears that Maliki is increasing his hold on the government and marginalising Sunnis. In a system devised under US occupation to divide power, Iraq has a Shia prime minister with Sunni and Kurd deputies, a Kurdish president with Shia and Sunni vice-presidents, and a Sunni parliament speaker.
