The Congress on Tuesday slammed the Centre for refusing to renew FCRA registration of Nobel Laureate Mother Teresa's Missionaries of Charity over "some adverse inputs".

"Nothing can be more shocking than denying future foreign contributions to the Missionaries of Charity in Kolkata, West Bengal. This is the greatest insult to the memory of Mother Teresa who devoted her life to care for the 'poor and wretched' of India," Congress leader P Chidambaram tweeted.
