The fight between Union ministers for agriculture and environment, Sharad Pawar and Jairam Ramesh, over whether to clear genetically modified crop Bt brinjal for commercial use sharpened on Friday with the Congress backing the latter to the hilt. [...] ”It is not an issue between the agriculture and environment ministries. The government retains an overriding remit if larger issues of public interest are involved. To that extent, the environment minister is absolutely right in interpreting the responsibility of the government,” Congress spokesperson Manish Tiwari said.
