Explanation
Storage limitation is one of the principles of data protection under the UK GDPR. It means that personal data should not be kept in a form that allows identification of data subjects for longer than is necessary for the purposes for which the data are processed. The UK GDPR does not specify any fixed time limits for different types of data, but rather requires data controllers to determine and justify the appropriate retention periods for their processing activities, taking into account factors such as the nature, scope, context and purposes of the processing, the risks to the rights and freedoms of data subjects, and the legal obligations and expectations of the data controller. Data controllers should also have a policy setting out standard retention periods where possible, and review the data they hold regularly to ensure that it is erased or anonymised when it is no longer needed. Data subjects have the right to request the erasure of their personal data if the data controller no longer has a lawful basis or a legitimate interest for keeping it. The UK GDPR allows for some exceptions to the storage limitation principle, such as when the personal data is processed solely forarchiving purposes in the public interest, scientific or historical research purposes, or statistical purposes, subject to appropriate safeguards for the rights and freedoms of data subjects.

Explanation
The definitions of "public authority" and "public body" for the purposes of the UK GDPR and the Data Protection Act 2018 are found in the Freedom of Information Act 2000 and the Data Protection Act 2018 respectively. Section 7 of the Data Protection Act 2018 provides that a public authority or a public body is one that is listed in Schedule 1 to the Freedom of Information Act 2000, or is designated by an order under section
5 of that Act. However, a court or tribunal acting in its judicial capacity is not considered a public authority or a public body under the Data Protection Act 2018. References:
* Section 7 of the Data Protection Act 20181
* Schedule 1 to the Freedom of Information Act 2000

Explanation
The UK GDPR and the Data Protection Act 2018 set a maximum fine of £17.5 million or 4% of annual global turnover, whichever is higher, for infringements of the data protection principles, the rights of data subjects, or the rules on transfers of personal data to third countries. This is the higher maximum penalty that applies to the most serious breaches of the UK GDPR. A security breach that exposes the details of a hundred thousand members of the public would likely fall under this category, as it would compromise the confidentiality and integrity of personal data, and potentially cause significant harm and distress to the data subjects. Therefore, the maximum fine that the UK public body could receive for this breach is £17.5 million or 4% of gross annual turnover, whichever is higher. References:

Explanation
CCTV images recorded in a supermarket are personal data as they can be used to identify living human beings, either directly or indirectly, by their physical appearance, clothing, accessories, or other distinctive features.
Personal data is defined in Article 4(1) of the GDPR as "any information relating to an identified or identifiable natural person". The GDPR applies to the processing of personal data by automated means, such as CCTV cameras, or by non-automated means that form part of a filing system, such as paper records. The other options are incorrect because:
* CCTV images are not special category data as they do not reveal any of the sensitive information listed in Article 9(1) of the GDPR, such as racial or ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, health, sex life or sexual orientation, or biometric or genetic data.
Special category data is subject to stricter conditions and safeguards under the GDPR, as it poses a higher risk to the rights and freedoms of individuals.
* CCTV images are not biometric data in the terms of the definition stipulated in the GDPR. Biometric data is defined in Article 4(14) of the GDPR as "personal data resulting from specific technical processing relating to the physical, physiological or behavioural characteristics of a natural person, which allow or confirm the unique identification of that natural person, such as facial images or dactyloscopic data". CCTV images do not result from specific technical processing, nor do they allow or confirm the unique identification of a natural person, unless they are combined with other data or identifiers.
* The GDPR is not only engaged where CCTV images are accompanied by text or other identifier. The GDPR applies to any information that relates to an identified or identifiable natural person, regardless of whether it is accompanied by text or other identifier. CCTV images can relate to an identifiable natural person even if they do not contain any text or other identifier, as long as there is a possibility to single out or link the person to other data or factors.

Explanation
If a complainant disagrees with the decision of the UK's supervisory authority, which is the Information Commissioner's Office (ICO), they have the right to appeal to the First Tier Tribunal (Information Rights).
The tribunal is an independent body that can review the ICO's decision and either uphold it, vary it or cancel it. The tribunal can also direct the ICO to take certain actions, such as issuing a decision notice or an enforcement notice. The appeal must be lodged within 28 days of receiving the ICO's decision, using the notice of appeal form and providing the relevant documents and grounds for appeal. The tribunal will then notify the ICO and the complainant of the appeal and the procedure for dealing with it. The tribunal may hold a hearing to examine the evidence and arguments of both parties, or decide the case on the basis of written submissions only. The tribunal will issue a written decision, which will be sent to both parties and published on the tribunal's website. The tribunal's decision can be further appealed tothe Upper Tribunal on a point of law, with the permission of the First Tier Tribunal or the Upper Tribunal. References:
