New Delhi, Aug 28 (IANS): The BJP's reverses in assembly by-elections marks the waning of the Narendra Modi "euphoria" and shows voters are getting disenchanted with the new regime, the CPI-M said Thursday.

CPI-M mouthpiece "People's Democracy" said in an editorial that the Modi government and the BJP "suffered a major setback in the recently held by-elections in Bihar, Karnataka, Madhya Pradesh and Punjab.

"Of a total of 18 seats, the BJP could only win 10," it said, adding that it bagged only six of the 10 seats that went to the polls in Bihar where - like elsewhere in the country - it swept the Lok Sabha polls.

Both in Madhya Pradesh and Karnataka, it lost one sitting seat each, it added. "This marks a significant trend of reversal from the patterns seen in the general elections and the waning of the Modi 'euphoria'."

Earlier, in by-elections in Uttarakhand, the Bharatiya Janata Party lost all the three seats that went to the polls.

"These results ... are a pointer to the fact that people have realised ... that the real agenda of the Modi government is completely different from the issues on which the (Lok Sabha) election campaign was mounted," said the Communist Party of India-Marxist.
