The twitter handle of the PDP president is being operated by her daughter Iltija Mufti after the former was placed under preventive detention hours ahead of the Centre abrogating Article 370.
Iltija said she has met her mother about six times since she was detained.
It would be the first time that the leaders would spend the harsh winter months in the Valley rather than moving to the warmer winter capital, Jammu.
Sheikh Mushtaq Ahmad, the father of Deputy Mayor Sheikh Imran, came to meet his son for the first time at the MLA hostel. He said the detained politicians are getting a bad deal.

Jitendra Singh said the narrative on J& K has to change so that the fruits of good governance and development reach to the people.

The Centre will be responsible if anything happens to Mehbooba, the president of the PDP, Iltija Mufti has written in a letter to the Srinagar deputy commissioner.
The administration had earlier given permission to a delegation of PDP leaders to meet Mufti, but the party deferred the proposed visit following serious differences within its camp.
