Several Buddhist groups in Sri Lanka have attacked the government for allowing the Sri Lankan national anthem to be sung in Tamil, Ceylon Today reported.
The groups accused the government of "acceding to Liberation Tigers of Tamil Eelam sentiments".
The Ravana Balaya said it is organising a "massive protest" against the government's decision.
The group said the anthem cannot be sung in two languages as stated in the constitution, accusing President Maithripala Sirisena of pandering to Tamils, especially the TNA and "pro-tiger" groups who had voted for him.
"This is why beside mature politicians like the TNA Leader R Sambanthan, there are crooks like Democratic People's Front leader Mano Ganesan placed in the National Executive Council," Ravana Balaya's leader Iththekande Saddhatissa said.
The Bodu Bala Sena's general secretary, Gnanasara said the ruling coalition had violated the constitution twice.
