The U.K's Home Secretary, Theresa May, will make the announcement in the House of Commons, according to McKinnon's attorney, Karen Todner, in a statement released Monday.

McKinnon, 46, of North London, has fought a decade-long battle against extradition in the courts with several lines of argument. His current request is for the U.K. to block extradition on medical grounds since he has been diagnosed with Asperger's syndrome, a neurological disorder related to autism characterized by deficiencies in social interaction, as well as depression.

McKinnon said he would like to face trial in the U.K., but the Crown Prosecution Service has said U.S. prosecutors have jurisdiction and the majority of evidence is in the U.S.

The case has drawn celebrity support from Pink Floyd guitarist David Gilmour as well as Sting, lead singer and bassist for The Police. It also came up in conversation when Prime Minister David Cameron met with U.S. President Barack Obama at the White House in July 2010, but to no resolution.

McKinnon's plight prompted a British inquiry over the fairness of the U.S.-U.K. extradition treaty, which concluded in October 2011 that the U.K. and U.S. legal systems are similar, with no differences in how an arrest is justified.
