The politician died in Kloof Hospital in Pretoria on Wednesday morning, confirmed Mpho Mosimane, who was the spokesperson for the group of 101 stalwarts and apartheid activists who had asked last year for Jacob Zuma to step down.
Mosimane said they would issue a statement later in the day.
Skweyiya was born in Simon’s Town, Cape Town, in 1942.
After becoming an MP in 1994, Skweyiya immediately assumed the position of public service and administration minister.
In 1999, he was appointed social development minister, a post he held for 10 years.
In 2009, Skweyiya was appointed as high commissioner of South Africa to the UK and Ireland.
On his return to the country, he remained an active ANC veteran.
