Former deputy economic development minister Enoch Gondongwana has stepped down as a Member of Parliament, according to a report on Thursday.

Gondongwana was facing a misconduct probe by the ethics committee for allegedly not properly declaring his business and financial interests.

The registrar of Parliament's joint ethics committee, Fazella Mahommed, told MPs on Wednesday that Gondongwana had informed the legislature of his decision to step down, reported the Sowetan newspaper.

"So that particular matter is now out of the hands of the committee," said Mahommed.

Gondongwana and his wife are embroiled in an inquiry into the disappearance of about R100 million of the SA Clothing and Textile Workers' Union's pension fund.

He resigned as deputy minister last month.
