# 2005 South African floor-crossing window period

The 2005 floor crossing window period in South Africa was a period of 15 days, from 1 to 15 September 2005, in which members of the National Assembly and the provincial legislatures were able to cross the floor from one political party to another without giving up their seats. The period was authorised by the Tenth Amendment of the Constitution of South Africa, which scheduled regular window periods in the second and fourth September after each election. The previous general election had been held on 14 April 2004.
In the National Assembly, the floor-crossing expanded the African National Congress' (ANC) representation from 279 to 293 seats, giving it control of almost three-quarters of the 400-member house. Other existing parties mainly lost seats, with several entirely new parties being created; still-existing parties created in 2005 include the National Democratic Convention
Seven of the nine provincial legislatures were also affected, with only the Free State and North West legislatures remaining unchanged. In both the KwaZulu-Natal Provincial Legislature and the Western Cape Provincial Parliament the ANC received enough members to move from a plurality to an absolute majority; in KwaZulu-Natal it gained two members to control 40 of the 80 seats, while in the Western Cape it gained five, to give it 24 of the 42 seats.
This window period also saw the final demise of the New National Party, in which all its members crossed the floor, mostly to become ANC representatives.
The tables below show all the changes; in those provinces not listed there was no change in the provincial legislature.
