Panaji, May 23 (IANS): Narendra Modi has the aura of a "rockstar", but he should also behave like the prime minister of India and not as the prime minister of the BJP during foreign tours, the Congress said here on Saturday.

Addressing a press conference at the party's state headquarters here, Congress spokesperson Tom Vadakkan said it was wrong of the prime minister to say that Indians considered it a curse to be born in India before 2014, the year when the Modi-led government rode to power in the general election.

"He's a rockstar, yes I agree," Vadakkan said, when told about the excitement Modi generated during his foreign visits.

The spokesperson, however, sought to remind Modi that he was the prime minister of India and not of the Bharatiya Janata Party.

"He is the prime minister of this country. He is not the prime minister of the BJP. He is the prime minister of the country. He has to hold that in his mind as he speaks.

"He talks on foreign soil, he criticises, we accept it. We do complain, but you can't say that to be born in India before 2014 was a curse. If this is what the prime minister says, we have nothing to add," the Congress leader said.
