The full list, left to right, is: Mridula Sarabhai; Abdul Samad Khan Achakzai; Bakshi Ghulam Mohammad; Jawaharlal Nehru; Abdul Ghaffar Khan (also known as Badshah Khan and as the 'Frontier Gandhi') who is holding Rajiv Gandhi; Indira Gandhi; behind her, Sheikh Abdullah; an unidentified couple; B.P.L. Bedi; and Freda Bedi. More details about all of these below.
A poor quality copy of this photo (without the writing in Urdu) has been circulating on social media for a while and is included in Andrew Whitehead's 2019 biography of Freda Bedi, The Lives of Freda. This copy is courtesy of Ayaz Khan Achakzai, whose grandfather features in the photograph - his family in Quetta have a copy.
The inscription in Urdu reads: 'Dar Bangla Afzal Baig Srinagar 1945'. Mirza Afzal Beg was one of Sheikh Abdullah's closest political colleagues.
Nehru was released from jail by the British on 15th June 1945, as the Second World War was drawing to a close. On 19th July, Nehru travelled to Kashmir where he was reuinted with Indira, his daughter, and they went trekking for twelve days. On 1st August he came to Srinagar for a reception and river procession - Badshah Khan was also in Srinagar at the time. On 4th August, Nehru addressed the annual session of the Jammu and Kashmir National Conference, Sheikh Abdullah's political party, at Sopore near Srinagar. On about 9th August, Nehru left Srinagar for the Kashmiri resort town of Gulmarg with Indira and her baby son, Rajiv - and a week or so later, he went to Murree and on to visit the North West Frontier Province.
So this photo was taken in early August 1945, almost exactly two years before Nehru became the first prime minister of independent India.
