On 3 July 2025, there was published on legislation.gov.uk a draft of The Markets in Financial Instruments(Miscellaneous Amendments) Regulations 2025 together with a draft explanatory memorandum.

The draft statutory instrument retains certain key definitions within the UK version of Commission Delegated Regulation (EU) 2017/565, otherwise known as the MiFID Organisational Regulation or MiFID Org Reg for short, in domestic financial services legislation. It also modifies definitions already in the Financial Services and Markets Act 2000 Regulated Activities Order 2001 to clarify the terminology.

A subsequent commencement statutory instrument will be made to revoke the MiFID Org Reg and bring into force this draft statutory instrument. HM Treasury will do this in co-ordination with the Financial Conduct Authority and Prudential Regulatory Authority implementing rules to replace the firm-facing provisions from the MiFID Org Reg.
