Is there a term limit on the prime minister of great Britain?

Answer 1

No. The Prime Minister serves at Her Majesty's pleasure, meaning he or she holds their office from the day they are appointed until the day their resign, die or dismissed. In modern Britain, this means a Prime Minister holds office until he or she either loses a general election (like Gordon Brown), resigns voluntarily mid-term (like Tony Blair in his third term) or is forced out of office, either by a motion of no confidence in the House of Commons or as a result of losing the leadership of their political party.

All though in theory this means a Prime Minister at the head of a popular party can remain in power for a very long time, in practice only two modern Prime Ministers have been able to survive in office for a decade. No Prime Minister of the modern era has been able to hold office long enough to achieve a fourth term in power, and only two have made it to a third term. As such commentators often say that there is an effective term limit of 10 years on any Prime Minister's power as by that point, they are likely to be losing popularity both with the public and with their party.
