[25 marks]In 2018, Albert purchased Blackacre, registered with absolute title at HM Land Registry. The transfer deed contained a covenant restricting use to residential purposes only. In 2020, Albert granted a 21-year lease to Bella, who registered it as a noted interest. Bella immediately sub-let the property to Charlie for commercial use. In 2021, Albert sold the freehold to Diana, who was unaware of Charlie's commercial activities. Diana's solicitor failed to investigate the sub-lease arrangements. Diana has now discovered Charlie's breach of the restrictive covenant and seeks to evict both Bella and Charlie. Meanwhile, Charlie claims he has acquired rights through proprietary estoppel, having spent £50,000 on commercial improvements after Albert assured him the restriction would not be enforced. Bella argues her lease takes priority over the covenant. Advise Diana on her prospects of success in removing Bella and Charlie, considering the principles of registered land and the protection of interests.
