The 22nd Amendment to the US Constitution limits serving as President to 2 terms or no more than 10 years.
George Washington was elected President of the United States twice, serving nearly 8 years as president.
The 22nd amendment restricts a president to serving 2 terms or 10 years.
The 22nd Amendment limits the number of terms a US president can be in office. This had a great impact in America because presidents are not able to hold onto power for long periods of time and it forces citizens to choose new leaders.
In order to serve 6 years, a president would either have to spend two years completing the term of the previous president and then be elected to a term of his own, or else leave office after serving two years of his second term. Lyndon Johnson came the closest to serving 6 years - about 2 months over. Coolidge served about 6 1/2 years. I believe all the rest who served more than 4 years served seven or more.
The Twenty-Second Amendment (Section 1), ratified in 1951, limits the US President to two terms of office.Amendment 22, Section 1No person shall be elected to the office of the President more than twice, and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once. But this article shall not apply to any person holding the office of President when this article was proposed by the Congress, and shall not prevent any person who may be holding the office of President, or acting as President, during the term within which this article becomes operative from holding the office of President or acting as President during the remainder of such term.
The 22nd Amendment of the United States Constitution limits the presidency to two terms, with a maximum of eight years in office, to prevent any president from serving for more than 12 years. Therefore, a president can only serve for 12 years if they are elected to two consecutive terms and then assume the presidency due to their predecessor's death or resignation.
If a President dies in office with less than 2 years remaining in his (or her) term, the VP would take over. They then could run for President 2 times, thus serving up to 10 years.
The 22nd amendment
If elected, a president can serve for two consecutive terms of four years each. If the president resigns or dies, and the vice president becomes president, he can serve out the remaining term of the former president. If the remaining portion of the term is less than two years, the new president can then run for and be elected to two consecutive terms of four years each. Short version- not more than 10 years with two years as a replacement for the president and eight years as an elected official.
The 22nd amendment limits a president to two terms or 10 years if he takes over for another president during that president's term of office. In other words, if someone takes over as president with more than 2 years left on the previous president's term of office, they can only serve 1 additional term elected on their own; they cannot be elected to a second term unless they served less than 2 years of the previous president's term of office.
The UK does not have a president, but I guess you're aiming at the Prime Minister. The current Prime Minister, David Cameron, has been in power since 2010. The longest serving PM was Sir Robert Walpole, serving more than 20 years (1721-1742).
