Media organisations need not belong to IPSO or IMPRESS (the two UK press regulators).

If you wish to complain to a newspaper or magazine about the standards it has applied when creating its journalistic output, and it does not belong to IPSO or IMPRESS, you will need to use its own procedures for raising your complaint directly.

Of the major national newspapers, the Guardian, the Financial Times, and the Independent do not belong to IPSO or IMPRESS. Instead, they have their own internal complaints procedures.
