Prime Minister Manmohan Singh today.
Tripathi, however, said the meeting has nothing to do with the stand-off between his party and the Congress and the issue was not discussed.
He said his meeting with the Prime Minister was in the capacity as Chairman of the Nepal Democracy Solidarity Committee India in which all political parties and civil society groups are represented.
Tripathi said he discussed the situation in Nepal with the Prime Minister.
"We discussed the situation in Nepal. The meeting has nothing to do with the crisis involving the Congress and NCP," he said.
The meeting of Tripathi, who is NCP spokesman and also Rajya Sabha member, took place in the backdrop of the party's decision to pull out of the UPA government and support it from outside in protest against the way the party was treated by Congress, creating fresh trouble for the ruling coalition.
