President Cyril Ramaphosa says there is no part of South Africa's land that can be allowed to secede.

Ramaphosa said this in criticism of the planned trip to Washington D.C by the Cape Independence Advocacy Group, a pressure group that is seeking to secede the Western Cape from the rest of South Africa.

The Cape Independence Advocacy Group this week notified South African authorities of its intention to send a delegation to the U.S. to meet with U.S. officials and other politically connected persons.

The mission intends to lobby for the secession of the Western Cape and campaign to force the Western Cape Premier to call a referendum on Cape Independence.

The discussions are also expected to include contingency plans to hold a private referendum should the Premier continue to refuse to consult the Western Cape people on the matter, the Group says. 

President Ramaphosa's spokesperson, Vincent Magwenya says the South African leader takes a very strong dim view of the group's planned visit to the U.S.

''Our constitutional democracy that we forged in 1994 created a unitary state and non-racial society that recognises and protects our unity in diversity. From Musina to Cape Town, we are one democratic society that should never be allowed to fall under the chasm of race divides. There is no part of our beautiful land that can be allowed to secede'', Magwenya said.

Magwenya said that President Ramaphosa has reiterated that as people exercise their constitutional rights, they must not do so in a manner that undermines and subverts constitutional democracy in South Africa. 

''We should all be actively engaged in building a better South Africa in the face of unpredictable geopolitical dynamics'', he said.

The Cape Independence Advocacy Group lists "stagnated economy, unemployment, corruption, violent crime, ballooned national debt and the government's alleged abandoning of ideals of the rainbow nation," as some of the reasons for seeking independence
