Which aspect applies to a PLC's requirement for a company secretary?

A public limited company (PLC) is required to have a company secretary to ensure compliance with legal regulations and to manage corporate governance matters effectively. One of the key requirements for a company secretary in a PLC is that they must possess the necessary qualifications. This typically means being a chartered secretary or having relevant experience and expertise in statutory requirements and corporate governance.

Having a qualified company secretary is essential because this individual plays a critical role in maintaining the company's records, filing necessary documents with regulatory authorities, and ensuring that the company adheres to legal obligations. The expertise required is necessary for the smooth functioning of the company, particularly given the complex regulations that govern PLCs.

In contrast, the other options do not align with the requirements for a PLC's company secretary. For instance, the secretary does not have to be the CEO, as these roles are typically distinct, and the company may choose someone with the appropriate expertise separate from the executive leadership. Additionally, having an untrained person or someone under the age of 18 serving as a company secretary would not meet the legal requirements or the standards expected in corporate governance. Hence, the emphasis on the need for a qualified professional is paramount.
