Sao Hom Hpa, the Sawbwa of Hsenwi, in London for the Burma Round Table Conference 1931-2.

The Burma Roundtable Conference paved the way for Burma's separation from India, the 1935 constitution, and the semi-elected governments of 1937-42.
The Sawbwa of Hsenwi was there in an advisory role to the the Sawbwas of Hsipaw and Yawnghwe.
The Burma delegation included about two dozen other prominent political figures, including U Chit Hlaing, U Tun Aung Gyaw, U Maung Gyee, Dr Thein Maung, Saw Sydney Loo-Nee, and Miss May Oung (Daw Mya Sein).
