Prime Minister Manmohan Singh on Wednesday called up Trinamool Congress chief Mamata Banerjee after which the key United Progressive Alliance ally decided to attend a meeting of the ruling coalition in Delhi on July 14.
"Prime Minister talked to Mamata Banerjee over phone," party Rajya Sabha MP Kunal Ghosh told PTI from North Bengal.
Banerjee has asked Railway Minister Mukul Roy to attend the UPA meeting on Saturday, he said.
"It will be after a long gap that Trinamool Congress will be attending a UPA meeting which is a significant development," he said.
Noting that Trinamool Congress has not taken any decision on its stand on the presidential and the vice-presidential elections, Ghosh said "whatever decision the party takes will be announced."
Banerjee, now in North Bengal, will visit Kalimpong on Friday. She was being accompanied by Roy.
Trinamool Congress had earlier said that Banerjee would announce the party's decision on the presidential poll three days ahead of the election on July 19.
