BJP on Saturday hit out at the Congress and CPI(M) for engaging in politics of convenience and opportunism in West Bengal and Kerala and said their days are numbered. <br/><br/>Union Minister and senior party leader Ananth Kumar told a meet-the-press programme in Thiruvananthapuram that while in West Bengal, there is direct alliance between Congress and CPI(M), in Kerala there was an indirect, underground and hidden alliance between the two parties.<br/><br/>He said, the common man has understood this hypocrisy. NDA's endeavour was to see that the state gets a new dispensation which would ensure good governance, development and people's welfare, he said.
