West Bengal Chief Minister Mamata Banerjee on Sunday wrote to Prime Minister Narendra Modi, requesting him to waive all forms of taxes and customs duty on equipment and drugs being used to fight the Covid-19 pandemic.

Banerjee also urged Modi to strengthen health infrastructure and augment supplies of equipment, medicines and oxygen for treatment of coronavirus-positive patients. "A large number of organisations, individuals and benevolent agencies have come forward to donate oxygen concentrators, cylinders, containers and COVID-related drugs. "Many of the donors have approached the state government to consider exemption of these from customs duty, SGST, CGST, IGST," she said in the letter.
