Singh also urged the DMK chief to use his good offices to persuade K. Thiagarajan (Thiagu), general secretary, Tamil National liberation Movement, to call off his fast. Thiagarajan is on hunger-strike, demanding that Manmohan Singh not attend the CHOGM to be held in Colombo this November. On Monday, DMK's leader in parliament T.R. Baalu met the prime minister and conveyed the feeling of Karunanidhi and the DMK that he should not attend the summit in Colombo.
