Explanation:

• The Windrush generation refers to the immigrants who were invited to the UK between 1948 and 1971 from Caribbean countries such as Jamaica, Trinidad and Tobago and Barbados. 
• The name derives from the ship MV Empire Windrush, which on June 22, 1948, docked in Tilbury, Essex, bringing nearly 500 Jamaicans to the UK.
• While a large proportion of them were of Jamaican/Caribbean descent, they also included Indians and other South Asians.
• A Commonwealth citizen is a national or citizen of any of the 54 member states of the Commonwealth of Nations. In some member countries, citizens from other Commonwealth states are entitled to certain rights, including eligibility to vote in elections and serve in government positions. The status is most significant in the United Kingdom, and carries little or no privileges in many other Commonwealth countries.
