Senior BJP leader and former Union minister Sartaj Singh Thursday switched over to the Congress after his name did not figure in the ruling party's third list for the November 28 Madhya Pradesh Assembly polls. Singh, two-time MLA from Seoni-Malwa who wept openly after the BJP snub, was immediately named as the Congress' nominee for the Hoshangabad Assembly seat in the opposition party's fifth list comprising 16 candidates. Singh holds sway in the Hoshangabad region and had defeated late Congress stalwart Arjun Singh from there in 1998.
