With Tamil Nadu's assembly polls only six months away, the CPI, CPI-M, the MDMK and the Dalit party VCK on Monday launched the four-party People's Welfare Alliance (PWA).
They also released their common minimum programme.
Initiated a month back as People's Welfare Front, it morphed on Monday into the PWA.
MDMK chief Vaiko told the media that the PWA would agitate against the central government's economic policies like globalisation, liberalisation and privatisation as they affect the people of Tamil Nadu.
The PWA promises to take steps to prevent privatisation of public sector units and FDI in critical sectors, bring a Lok Ayukta in Tamil Nadu and increase government's infrastructure spending.
