Congress Vice President Rahul Gandhi on Wednesday met CPI-M General Secretary Sitaram Yechury and sought Left parties' support on an amendment to be moved by Jairam Ramesh to the Goods and Services Tax (GST) bills in the Rajya Sabha on Thursday.According to a source in the Communist Party of India-Marxist, Gandhi met Yechury in the afternoon on Wednesday."We will also move about 6-7 amendments. Since this is a Money Bill, so just like the Finance Bill that we passed some amendments, it will show that they don't have majority in the House. If the bill is returned with amendments, they have to take it back to the Lok Sabha," said the source who declined to be identified. Four GST bills are expected to be voted on in the Rajya Sabha on Thursday.Senior Congress leader Jairam Ramesh is likely to move an amendment which says that anything passed by the GST Council should also get parliamentary approval."There is only one amendment that was being planned by Jairam Ramesh, which is the one which says that anything passed by the GST Council should also get parliamentary approval," said Congress spokesperson Rajeev Gowda at a media briefing."It was discussed and a consensus emerged where it was decided that this amendment is not going to be taken forward as the Congress party's amendment," he added.
