The killer of Israeli Prime Minister Yitzhak Rabin has submitted a formal request for permission to marry.
Amir shot Rabin several times at a peace rally in 1995
Yigal Amir, who is serving a life sentence for the 1995 murder, has submitted his request to the Israeli prison authority.
Last week, the head of the authority said he would refuse any marriage request by Amir, following reports of his proposed marriage on television.
If his request is refused, Amir could take the issue to the High Court.
Israeli television reported that Amir, 34, intended to marry Larisa Trimbobler - an ultra-Orthodox Jewish immigrant from the former Soviet Union.
Ms Trimbobler, who has frequently visited Amir in prison, wanted to marry him for ideological reasons, Channel 2 said.
Amir, an ultranationalist Jew, said he killed Rabin to derail a land-for-peace deal between Israel and the Palestinians.
Israel's prisons chief Yaakov Ganot said last week that he had already instructed his legal aides to prepare a case to defend his decision to refuse Amir's request, in case the prisoner decided to appeal in court.

Experts say that the only argument that the prisons authority would be able to use to deny Amir's request would be based on security considerations.
Under Israeli law, all prisoners are allowed to marry and have children.
