Senior Congress leader Anand Sharma has launched a stinging attack on Prime Minister Narendra Modi over the lavish ‘Howdy, Modi!’ event in the United States on Sunday, reminding him that he is in the country as the Prime Minister of India and not to campaign for US President Donald Trump. In tweets posted late Sunday night, the Rajya Sabha MP criticised PM Modi for having “violated the time-honoured principle of not interfering” in another country’s election. Prime Minister Modi, in the US for a week-long visit, was joined by President Trump at a public event in Houston, Texas. PM Modi, who received a rockstar welcome, took the unusual step of introducing Mr Trump to a crowd of more than 50,000. In his introduction, PM Modi lavished praise on Mr Trump, whom he called “a very special person”. President Trump, a Republican, is seeking re-election next year. Mr Sharma, who pointed out that India’s relationship with United States had always been bipartisan, was left less than impressed at what appeared to PM Modi’s attempt to drum up support among Indian-Americans for Mr Trump. “Mr Prime Minister, you have violated the time-honoured principle of Indian foreign policy of not interfering in the domestic elections of another country. Our relationship with the United States of America has throughout been bipartisan, vis-a-vis Republicans and Democrats,” Mr Sharma wrote, adding, “Your actively campaigning for Trump is a breach of both India and America as sovereign nations and democracies”.
