Stella Assange says will seek a pardon for husband Julian

London: Stella Assange, the wife of WikiLeaks founder Julian, told Reuters on Tuesday they would seek a pardon after he agreed to plead guilty to violating US espionage law, bringing his long-running legal saga in Britain to an end.

Assange, 52, will plead guilty to a single criminal count of conspiring to obtain and disclose classified US national defence documents and is expected to be sentenced to 62 months of time already served at a hearing in Saipan in the Northern Mariana Islands.

He will then be free to return home to Australia.

Stella Assange, a lawyer who has worked on his campaign almost since the start of his legal battles, said she was elated at the move but still angry that he had been held for so long.

The couple married while he was in Belmarsh maximum security jail in London, and they had two children while he was holed up in the Ecuadorean embassy in London.

She said they would seek a pardon because the acceptance of guilt on an espionage charge was a "very serious concern" for journalists around the world. She also said they would launch a fundraising campaign as the flight from London to Saipan for a court hearing and then to Australia would cost around half a million US dollars.

"The fact that there is a guilty plea, under the Espionage Act in relation to obtaining and disclosing National Defence information is obviously a very serious concern for journalists and national security journalists in general," she said.

Elated, worried and angry

Stella Assange said she had always believed this moment would come but she would not relax until he had arrived in Australia, where he is expected on Wednesday. She said on Tuesday morning that she had still not broken the news to their children.

"I feel elated. I also feel worried, you know, because I'm so used to this. Anything could happen. I'm worried that until it's fully signed off, I worry, but it looks like we've got there," she said, speaking from Sydney.

"I'll really believe it when I have him in front of me and I can take him and hug him and then it will be real you know?"

The deal marks the end of a legal saga which has seen Assange spend more than five years in a British high-security jail and seven holed up in the Ecuadorean embassy in London following WikiLeaks' mass release of secret US documents - the largest security breaches of their kind in US military history.

Stella said Julian had been a "so much lighter" as the agreement became closer and they would likely spend time in Australia now - a good place, she said, to regain your health and sanity.

"I think that goes not just for Julian but for me as well," she said. "It's been a rough, very rough few years and we need some time."

First, she said they needed to raise money.

"It's Australian policy that he will have to pay his own return flight so he's had to charter a flight and so he will basically be in debt when he lands in Canberra.

"We're going to launch an emergency fund to try to get this money so that we can pay the Australian government back for his freedom flight.

"It's half a million US dollars."
