"There has been a tradition that we all have followed that when we are abroad we do not discuss the country's politics, do not criticise one another and instead speak for the country. Chidambaram has broken this custom. The more he is condemned for it, the less," BJP leader Yashwant Sinha told reporters here.
Chidambaram, who is in Davos to attend the World Economic Forum meet, criticised Modi over his model of development.
The former Finance Minister said Modi had laid out his political and economic vision for the country during the meeting of the BJP's National Council.
"Chidambaram has called BJP's economic vision 'blood-eyed'. He better knows what he means by it. But Modi has clearly spelt out his political and economic vision for the country in the national council's meeting and it points to a definite direction," he said.
