A judge in Pakistan has ordered the arrest of President Asif Ali Zardari's preferred candidate for prime minister, just a day after he was nominated.
Makhdoom Shahabuddin's arrest warrant is linked to imports of an illegal drug while he was health minister.
Parliament is due to vote on a new PM today to replace Yousuf Raza Gilani.
The Supreme Court disqualified him because of a contempt conviction.
It is not clear if the warrant will derail Shahabuddin's nomination.
Legal experts say that even if he is arrested, he could still be elected prime minister by parliament.
Shahabuddin is a senior figure in the ruling Pakistan People's Party who served in the cabinet of Benazir Bhutto and was most recently textiles minister in Gilani's administration.
