A group of 61 U.K. politicians submitted a petition via law firm Reed Smith to the U.S. Supreme Court in a bid to secure the release of a U.K. prisoner.

The move is the latest development in efforts to secure 84-year-old Krishna Maharaj's release from a Florida prison, where he has been incarcerated for 36 years for the murders of Chinese-Jamaican businessman Derrick Moo Young and his son Duane Moo Young.
