Leader of the Opposition (South Africa)

The Leader of the Opposition in South Africa is the leader of the largest political party in the National Assembly that is not in government. The House of Assembly was the most important House from 1910 to 1994 and the National Assembly from 1994. The leader of the opposition acts as the public face of the opposition, leading the Official Opposition Shadow Cabinet and the challenge to the government on the floor of Parliament. They thus act as a chief critic of the government and ultimately attempt to portray the opposition as a feasible alternate government.

The position of Leader of the Opposition in the National Assembly is currently held by John Hlophe of the uMkhonto weSizwe, who was appointed on 25 June 2024.

In the list below, when the office is said to be vacant, there was no opposition party with more than ten seats and no clear Leader of the Opposition has been identified. This was the case between the formation of the Hertzog–Smuts coalition in 1933 and the breakaway of the Purified National Party in 1934. It was also the case during the Government of National Unity between 1994 and 1996, when the National Party withdrew.

In the case of the Democratic Alliance, the Leader of the Opposition may have been the Parliamentary leader only, during a vacancy in the party leadership and the first part of their own tenure, before being confirmed as party leader by a party congress. Athol Trollip and Lindiwe Mazibuko (and Mmusi Maimane for a short period) have been Parliamentary leaders only, whilst the incumbent Federal Leader of the Democratic Alliance, Helen Zille, was not a member of Parliament.

Legal definition
Section 56 of the South Africa Act 1909, was amended by Section 1 (b) of the South Africa Act Amendment Act 1946. A salary was provided for the Leader of the Opposition and the office was given an official definition. "'For the purposes of this section the expression 'Leader of the Opposition' shall mean that member of the House of Assembly who is for the time being the Leader in that House of the party in opposition to the Government having the greatest numerical strength in that House and if there is any doubt as to which is or was at any material time the party in opposition to the Government having the greatest numerical strength in that House of Assembly, or as to who is or was at any material time the Leader in the House of such a party, the question shall be decided for the purposes of this section by the Speaker of the House of Assembly, and his decision, certified in writing under his hand, shall be final and conclusive'."

The current Constitution of South Africa makes provision for recognition of the Leader of the Opposition in Section 57(2): "'The rules and orders of the National Assembly must provide for … the recognition of the leader of the largest opposition party in the Assembly as the Leader of the Opposition.'" Rule 21 of the rules of the National Assembly provides in similar words that:

"'The leader of the largest opposition party in the Assembly must be recognised as the Leader of the Opposition.'"
