Such groups have a responsibility to get together and form a strong opposition, without which the government would go astray, he told journalists after opening a SLFP office at Horagasmandiya in Urubokka.
Rajapaksa said he was unaware of a group of opposition MPs’ getting ready to crossover and accept ministerial positions.
He claimed he was the only person not to betray the SLFP to the UNP, alleging that many in politics at present have done so, BBC Sandeshaya reported.
