Several members of the BJP gathered outside the residence of Congress MP DK Suresh here on Sunday to protest his recent statement that southern states would be forced to demand for a separate nation if the 'injustice' in distribution of funds is not rectified by the Centre. Protesters were heard shouting slogans 'Vande Mataram', 'Bharat Mata Ki Jai', 'down down D K Suresh' outside his residence in Sadashivanagar here.
