Labeled “India Out” the campaign is mainly being driven on social media, and hashtags #IndiaOut, #BoycottIndia and #BoycottIndianProducts have been trending on Facebook for the past few weeks.

Charging Indian interference in the election, members of the groups, based in and outside Bangladesh, suspect New Delhi has used its influence to tone down criticism of the balloting process by the United States and other countries.

More broadly, the boycott campaign has provided a focus for deep-seated resentment of India in Bangladesh, driven by border and water grievances and by a sense that India’s Hindu nationalist ruling party looks down on its Muslim neighbors.

As a result of the anti-India campaign, employees at several shops in Dhaka and Chittagong said they had seen a drop in sales of some Indian products such as cooking oil, processed foods, toiletry, cosmetics and clothing. Some Indian traders and vendors told VOA's Bangla Service, though, that they were not seeing any impact.

France-based Bangladeshi activist Pinaki Bhattacharya, one of those behind the campaign, said that since the 2014 general election, the Awami League has managed to win three "farcical" general elections with India's support.

The Bangladesh Nationalist Party, the largest opposition party in the country, boycotted the election after the Awami League refused to install a neutral caretaker government to oversee the voting. Its absence from the ballot left the ruling party with no effective opposition.

After all 300 seats contested were won by the AL-led alliance and “independent” candidates that support it, the US State Department said in a statement the elections had not been "free or fair".

The Home Ministry of Bangladesh has not responded to a VOA email requesting comment on the India Out campaign. But Alok Vats, a senior leader in India's ruling Bhartiya Janata Party, said the accusation that New Delhi interferes in the internal politics of Bangladesh is "not true at all."
