- A) Collective Responsibility: Both India and Britain adhere to the principle of collective responsibility of the executive to the legislature. This is a similarity. - B) Judicial Review: India's written Constitution and the powers granted to the Supreme Court and High Courts (Articles 13, 32, 226) establish a system of judicial review, allowing courts to declare laws and executive actions unconstitutional. In contrast, the UK's system lacks a formal written constitution and parliament is sovereign; courts cannot declare an Act of Parliament unconstitutional (though they can review executive actions and interpret laws). This is a major difference. - C) Bicameral Legislature: Both countries have a two- chamber legislature (Lok Sabha/Rajya Sabha in India, House of Commons/House of Lords in the UK). This is a similarity. - D) Real and nominal Executive: Both systems feature a nominal head of state (President/Monarch) and a real head of government (Prime Minister). This is a similarity.
