On 26 May 2023, there was published on the legislation.gov.uk website, The Insider Dealing (Securities and Regulated Markets) Order 2023.

This Order updates Schedule 2 of the Criminal Justice Act 1993 (CJA), bringing securities and markets on which an offence can be committed in the CJA broadly in line with the Market Abuse Regulation (MAR). The Order 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 MiFIR.
