The Opposition says it will submit a no-confidence motion against Justice Minister Harshana Nanayakkara to the Speaker of Parliament next week.

SJB MP Ajith P. Perera said the motion relates to the Minister's alleged failure to take responsibility over the Negombo Prison unrest, which resulted in the deaths of prison officers and inmates.

The motion was signed by opposition MPs, including Opposition Leader Sajith Premadasa, on 10 July.
