The three previous GB equality commissions, the Commission for Racial Equality, the Disability Rights Commission and the Equal Opportunities Commission, have been replaced by a single Equality and Human Rights Commission (EHRC) in October 2007, which can support complainants in legal proceedings, has enforcement powers of its own, and also has powers to promote and encourage respect for equality of opportunity through research, public comments and other methods. There is a separate Equality Commission for Northern Ireland, which has similar functions (and in places, greater powers relating to positive action) to those of the EHRC.
