South Africa's leading cement producer, PPC, said on Friday that it would convene a meeting of shareholders next month "to consider the removal of the entire existing board" after three shareholders holding a 10 per cent stake requested it.

The company said in a filing to regulators that the meeting "is likely to occur in the first half of December" and will also consider the "proposed elections of certain persons nominated" by the said shareholders. 

A further announcement will be made when the dates have been finalised, PPC added.
