Who has been the First Lord of the Treasury since November 28, 2022?

The correct choice is Rishi Sunak because he assumed the position of First Lord of the Treasury on November 28, 2022, following Liz Truss's resignation as Prime Minister. The position of First Lord of the Treasury is traditionally held by the Prime Minister in the United Kingdom and signifies the leader's role in overseeing the Treasury, which manages the country’s finances.

Prior to Sunak, both Boris Johnson and Liz Truss held the role, but they were in office during earlier periods. Theresa May and David Cameron also served as Prime Ministers in the past but are not associated with the current date referenced in the question. Sunak's leadership as of late 2022 marked a significant point in UK politics, reflecting ongoing changes and challenges faced by the government.
