Answer from Hansard

The Parliamentary Under-Secretary of State for Foreign, Commonwealth and Development Affairs (Uma Kumaran)

This Government inherited a situation from the previous Conservative Government where UK control over the vital UK-US military base in Diego Garcia was under threat. This is about the long-term safety and national security of the United Kingdom and the British people. Maintaining the long-term operational control and security of the base remains a top priority; that is the entire basis for the UK-Mauritius agreement. A financial element was a crucial part of that deal.
