Karnataka's ruling alliance of the Congress and HD Kumaraswamy's Janata Dal Secular reiterated a message of unity after a crucial meeting of its Coordination Committee yesterday. The two parties have been battling a perception of rift after controversy over a video that purportedly showed former Chief Minister Siddaramaiah expressing doubts about the longevity of the alliance. But it was Mr Siddaramaiah who chaired the crucial Coordination Committee meeting, where the Common Minimum programme was discussed and approved.
