What Does A No Brexit Deal Mean For Data Protection?

Despite the whirlwind of uncertainty surrounding the UK's departure from the EU without agreement (a "no deal" scenario), the UK government remains resolute that such an outcome is unlikely considering the mutual interests of the UK and the EU in securing a negotiated outcome before 29 March 2019. However should this not be the case, what would this mean for data protection in the UK?

Currently, the rules which govern the collection and use of personal data are set at an EU-level by the General Data Protection Regulation (GDPR). In the UK, the Data Protection Act 2018 (which came into force on 25 May 2018) incorporates and supplements the standards set out in the GDPR and ultimately provides for a comprehensive data protection framework.
