Kolkata, Asking Prime Minister Narendra Modi and Union Home Minister Amit Shah to share the criterion for sending Inter-Ministerial Central Teams (IMCT) in select districts including a few in West Bengal amid the Covid-19 pandemic, Chief Minister Mamata Banerjee on Monday said till then her government wouldn't be able to move ahead on the matter.

Banerjee said without "valid reason", the step to send IMCTs wouldn't be "consistent with the spirit of federalism".

In a Twitter post, she said the basis for sending the IMCTs was "unclear".

"We welcome all constructive support & suggestions, especially from the Central Govt in negating the #Covid19 crisis. However, the basis on which Centre is proposing to deploy IMCTs in select districts across India including few in WB under Disaster Mgmt Act 2005 is unclear," she said.

"I urge both Honb'le Prime Minister @NarendraModi Ji & Home Minister @AmitShah Ji to share the criterion used for this. Until then I am afraid, we would not be able to move ahead on this as without valid reasons this might not be consistent with the spirit of federalism, " she added.

Earlier, the Home Ministry said the Centre has formed eight IMCTs to make on-spot assessment of situation, issue necessary directions to state authorities for its redressal and submit their report to it.

According to the centre, such a decision was taken in the larger interest of the general public.
