They were a set of demands for constitutional reform in British India aimed at safeguarding Muslim political rights.
Key points of the Delhi Proposals:
Acceptance of joint electorates (instead of separate electorates) if certain conditions were met.
One-third representation for Muslims in the Central Legislative Assembly.
Separation of Sindh from the Bombay Presidency, establishing it as a full province.
Introduction of equal constitutional reforms in the North West Frontier Province (NWFP) and Balochistan, bringing them on par with other provinces.
The name "Dehla Azam Allama Iqbal Deht Proposal" appears to be a phonetic misinterpretation of "Delhi Proposals" and the leaders’ names (Quaid-e-Azam Muhammad Ali Jinnah and Allama Muhammad Iqbal).
Allama Iqbal, a prominent philosopher and poet, later presided over the Allahabad session in 1930, where he articulated the vision for a separate Muslim state.
