Politics of the United Kingdom
The UK Parliament is the supreme legislative body in the United Kingdom (i.e., there is parliamentary sovereignty), and Government is drawn from and answerable to it. Parliament is bicameral, consisting of the House of Commons and the House of Lords. There is also a devolved Scottish Parliament and devolved Assemblies in Wales and Northern Ireland, with varying degrees of legislative authority.
Legislatures of British India
A dyarchy is a system of shared government. In British India, the British government decided to share responsibilities with legislative councils in major provinces.
As a result of Montagu–Chelmsford Reforms, the British government decided to gradually grant self-governing institutions to India. The Government of India Act, 1919 established a bicameral central legislature and granted revenue shares to provincial legislative councils. The British government elaborated that the system would continue for at least 10 years until a review. The Swaraj Party and Congress Party, which enjoyed majorities in the councils, boycotted the dyarchy- arguing that the reforms once again did not go far enough. The Congress increased its non-cooperation movement. However, constitutionalists in parties like the All India Muslim League continued to advocate their constituents' interests within the councils.
