Government Legal Department (GLD)

Government Legal Department

The Government Legal Department (GLD) serves as the principal legal adviser to the UK Government. The core purpose of the GLD is to help the government to govern well, within the rule of law. The GLD is a non-ministerial government department and executive agency.

The GLD has more than 3,000 employees, around 2,500 of whom are solicitors or barristers.

The Government Legal Profession (GLP) is the collective network of qualified lawyers embedded across UK government departments and agencies, providing expert legal advice, litigation support, policy guidance, and compliance services to ensure the government operates within the rule of law.

Susanna McGibbon is the Treasury Solicitor and Permanent Secretary of the Government Legal Department. The Treasury Solicitor is the government’s most senior legal official 

Susanna took up the role of Treasury Solicitor and Permanent Secretary of the Government Legal Department on Monday 8 March 2021.

Her previous roles include:

  • Director General, Directorate B, Government Legal Department, 2018 to 2021

  • Role and Function: The GLD provides legal advice on the development, design, and implementation of government policies and decisions. It drafts secondary legislation and works with the Office of the Parliamentary Counsel on primary legislation. The department represents the government in court proceedings, offering litigation services for most government departments and agencies.
  • Structure: The GLD is organised into various teams:
    • Parliamentary and Advisory Teams: These provide legal advice across numerous policy areas, ensuring government actions are legally sound and compliant.
    • Litigation Group: Handles legal disputes in various courts, covering public and private law, and supports public inquiries.
    • Commercial Law Group: Focuses on commercial law issues, including procurement, contracts, intellectual property, and state aid to ensure value for money in public spending.
  • Leadership: The GLD is headed by the Treasury Solicitor, who also holds the title of His Majesty’s Procurator General. This role involves managing the department and reporting to the Attorney General for England and Wales.
  • Scope: Besides serving Whitehall departments, the GLD extends its services to other organizations like HM Revenue & Customs, MI5, MI6 and various other governmental bodies. It’s also involved in handling ownerless property (bona vacantia) in England, except in certain regions where it’s delegated.
  • Significance: Its work is critical for ensuring that government operations, policy-making, and legal proceedings are conducted within the rule of law. This includes both advising on policy legality and defending or bringing legal actions on behalf of the government.

We are the government’s principal legal advisers. Our core purpose is to help the government to govern well, within the rule of law.

We do this by providing legal advice on the development, design and implementation of government policies and decisions, drafting secondary legislation and working with Parliamentary Counsel on primary legislation, and representing the government in court.
