Bengaluru, Nov. 28 -- Amid a lingering tussle in Karnataka for the post of Chief Minister, Congress leader M Veerappa Moily on Friday expressed concern over the delay in resolving the issue and said the party leadership should step in immediately.

Moily, a former union minister, said that the party's "totally internal problem has blown up and now the castes have taken over, the Swamijis have taken over".

There has been a tussle within the Congress government in Karnataka amid speculation over a power-sharing agreement concerning Chief Minister Siddaramaiah and his deputy, DK Shivakumar.

Moily said the party's central leadership should immediately step in as a lot of confusion has been created and it should stop "this kind of lobbying"....
