Amid renewed political churn in Karnataka, Chief Minister Siddaramaiah is likely to visit New Delhi around May 6 to consult the party high command on a long-pending cabinet expansion. The move comes as several senior leaders head to the capital, signalling that a reshuffle may be imminent. The development has revived speculation over the ongoing power tussle within the Indian National Congress, particularly between Siddaramaiah and Deputy Chief Minister DK Shivakumar.
