What are the duties and responsibilities of a company secretary?

"As a company officer appointed to take on some of the duties of the directors. Whilst their remit can vary from company to company, the usual role of a secretary involves:

• Completing and filing the Confirmation Statement (previously known as Annual Returns) within the given deadline.
• Filing directors’ reports, financial statements, and auditor reports.
• Ensuring the safekeeping of all legal documents.
• Reporting any significant changes to Companies House.
• Arranging any meetings of the directors and shareholders, and ensuring the effective administration and minute keeping of these meetings
  

Although a company secretary may take responsibility for these duties, the directors remain legally responsible for the lawful running of the company and the preparation and filing of all returns and reports.".
