This marks his re-entry into frontline politics seven years after resigning post-Brexit referendum. Cameron's appointment is part of a major cabinet reshuffle by Sunak, which includes James Cleverly becoming the new Home Secretary, replacing the dismissed Suella Braverman.
Cameron's return, a rare instance of a former Prime Minister rejoining the government, has been met with mixed reactions. While centrist Tory MPs have welcomed it, Brexit supporters and the Liberal Democrats, citing his involvement in the Greensill scandal, have criticized it.
The reshuffle comes amid the Conservative Party's declining popularity and internal divisions. It also follows Braverman's controversial remarks on policing at a pro-Palestinian march, which led to her sacking.
This reshuffle is seen as an attempt by Sunak to revitalize his government and distance himself from previous Tory administrations. However, it has also been noted for the lack of women in the top four cabinet positions, highlighting the gender imbalance in the current government setup.
