On 17 April 2023, HM Treasury published a draft of the Insider Dealing (Securities and Regulated Markets) Order 2023, (the draft statutory instrument (SII)), along with a draft explanatory memorandum.

The SI updates Schedule 2 of the Criminal Justice Act 1993 (CJA) bringing the securities and markets on which an offence can be committed in the CJA  broadly in line with Market Abuse Regulation (MAR). The SI replaces the securities listed in Schedule 2 with the list of financial instruments found in Part 1 of Schedule 2 to the Financial Services and Markets 2000 (Regulated Activities) Order 2001. It also replaces the list of named trading venues with references to the definitions for regulated markets, organised trading facilities and multilateral trading facilities as used in MAR and the Markets in Financial Instruments Regulation.
