As the NEC met at St George's hotel in Pretoria East yesterday, a group of party supporters from the West Rand staged a protest outside the venue.
The protesters alleged that they had been fraudulently excluded from the process of nominating candidates for the regional leadership.
"There were some people who marched from West Rand," Magashule said.
"We have taken their grievances. We have decided to postpone all regional conferences which were supposed to take place this coming weekend."
The Gauteng regional conferences were seen as crucial by various ANC factions in Gauteng as they were going to determine their strengths ahead of next month's provincial conference, where premier David Makhura is expected to replace Paul Mashatile as ANC provincial chairman.
But it is the Eastern Cape that seems to be giving the ruling party its biggest headache.
A group of disgruntled party members have approached the South Gauteng High Court in a bid to have the party's Eastern Cape provincial executive committee disbanded in line with what they say were recommendations made in a report compiled by former transport minister Sbu Ndebele.
Ndebele was appointed to investigate problems in the province late last year following a disputed provincial elective conference where Mike Mabuyane defeated premier Pumulo Masualle in the race for provincial chairmanship.
Ndebele is reported to have recommended that the PEC be disbanded because it was elected at a violent conference where delegates threw chairs at, and assaulted, each other.
