Why did BJP send its troubleshooter to Manipur?

Assam chief minister Himanta Biswa Sarma, known as the BJP's troubleshooter in the Northeast, visited violence-hit Manipur on Saturday. It is believed that he was tasked with assessing the mood within the state unit of the saffron party in the wake of a "rebellion" by a section of legislators.

At least 10 Kuki-Chin-Zo MLAs, seven of whom are from Manipur's ruling BJP, had openly criticised the N Biren Singh government's handling of the situation.
Soon after violence broke out in early May, they wrote to Union home minister Amit Shah demanding a separate administration for the hill districts. The "rebel MLAs" alleged state government had failed to protect the Kukis.
Ten hill districts of Manipur are home to Naga and Kuki tribes, accounting for 90 percent of the total land area in the state while the majority Meitei population largely lives in the valley comprising the remaining six districts.

Speculation was rife about a possible change of guard after Shah had announced a series of measures to restore peace in Manipur in early June. However, BJP chief JP Nadda recently ruled out the possibility of a leadership change at this juncture.
On Saturday, the Centre constituted a committee headed by Manipur Governor Anusuiya Uikey to facilitate a dialogue between Meiteis and Kukis. The CM is a member of the panel.

"During my stay here, I met the honourable chief minister, his cabinet colleagues, our party leaders and civil society organisations...Whatever I have learnt during the day, I will report the same to the honourable Union Home Minister for further necessary actions," Sarma, who also heads the BJP-led North-East Democratic Alliance (NEDA), said.
The Assam CM said that the Manipur BJP should not "hesitate to ask what is needed and he will make sure those requirements are met", a senior party leader told PTI.
