The Rashtriya Swayamsevak Sangh (RSS) denies operating abroad, even as government reports in the US, UK, Mauritius and Australia flag the influence of Hindutva groups on their social and political landscapes. As a new database identifies over 2,500 organisations linked to the RSS, including more than 200 operating outside India, our investigation shows that organisations overseas claiming to have no formal links to the RSS are actually working with the RSS and its affiliates.
