Criminal Court on Tuesday ended the hearings on the trial of former vice president Ahmed Adheeb Abdul Gahfoor over the alleged assassination attempt on the president.
Adheeb and two of his former bodyguards have been charged with terrorism over the blast aboard the presidential speedboat in September last year which authorities have now confirmed as a plot to kill president Abdulla Yameen Abdul Gayoom.
President Yameen escaped unhurt but his spouse Fathimath Ibrahim and a presidential aide was injured in the blast.
The closing arguments were heard behind closed doors after the judge cited national security.
Adheeb was handed a 10 year prison sentence on Monday after the Criminal Court found him guilty of possessing a hand gun.
Adheeb was found guilty after two witnesses testified that they had seen the ex-VP with the handgun during the mass opposition rally on May day last year.
In addition to the terrorism charge, the ex-VP is also facing massive corruption charges.
