Enoch Nkwe has resigned as South Africa 's assistant coach, Cricket South Africa have confirmed.
The 38-year-old, who initially joined the South Africa setup as interim team director in 2019, informed the CSA earlier this week of his intention to leave.
After discussions between the two parties, Nkwe has officially stepped down, with a statement from the CSA revealing that he has "raised concerns about the functioning and culture of the team environment."
In that statement, they said: "While every effort was made to retain his services, Enoch has decided to focus on personal growth and professional development.
"This affords him the opportunity to return to the system in the future with a better sense of himself and being certain of the direction of his career.
"He has emphasised his unwavering commitment to SA cricket and especially the men’s team as they embark on a key tour to Sri Lanka in preparation for the T20 World Cup in October.
"The Board engaged with Enoch to explore whether there was a way to retain his services but this was unsuccessful.
"During these discussions he also raised concerns about the functioning and culture of the team environment.
"The Board will be taking the necessary steps to investigate and address the issues raised by Enoch. We will not be commenting further on this until the process has been completed."
According to ESPNcricinfo, Nkwe decided to resign after 'differences of opinion' with South Africa's head coach Mark Boucher.
It is noted that these issues were not to do with race, after Boucher issued an apology earlier this month for "singing offensive songs" and "using offensive nicknames".
Pholetsi Moseki, CSA's acting CEO, told ESPNcricinfo that the organisation will investigate Nkwe's concerns in depth.
"The biggest challenge is the timing of this because the last thing we want is to distract the team's preparation for the T20 World Cup," Moseki said.
"But at the same time we want to get to the bottom of this. We can't sweep it under the carpet.
"All parties involved in the national team will need to be interviewed and we want to give them an opportunity to respond to any of Nkwe's concerns.
"We need to know how the team is functioning and if there are any issues.
"We want to take this matter forward and we need to be cognisant of everything that is going on. There is a lot happening at the moment."
