Step-by-step explanation:
Based on the provided text, Sebastian is being nominated for the post of Prime Minister.
In democratic systems like the United Kingdom, leadership roles such as the Prime Minister can come about through various means. For example, during World War II, Winston Churchill was appointed as the new Prime Minister.
