If a vacancy in the leadership occurs while the Labour Party is in government, then the Cabinet, in consultation with the National Executive Committee of the Labour Party, chooses a new leader, who serves until a new leader is elected. To date, the only Deputy Leaders who have gone on to become the elected leader of the Labour Party are Clement Attlee and Michael Foot. Margaret Beckett briefly served as Labour leader following the unexpected death of John Smith in 1994. Harriet Harman was leader after Gordon Brown resigned in 2010
Leader of the New Zealand Labour Party there must be a caucus vote to endorse the Leader; if the Leader fails to receive endorsement then an election is triggered. When the Labour Party forms the Parliamentary Opposition, the Leader of the Party usually acts as the Leader of the Opposition, and chairs a Shadow Cabinet. Concordantly, when the party is in Government, as it currently is, the Leader generally becomes the Prime Minister of New Zealand. Unique to Labour, the party's caucus possesses the right to elect MPs to Cabinet, rather than the Leader choosing them. The practice began following the 1940 leadership election. Michael Joseph Savage
