Trade unions may be invariably described as pressure groups; these organisations should be mentioned at the list of trade unions in the United Kingdom article, not here.
There are many pressure groups around the world. This is a list of pressure groups in the United Kingdom. Based on their relationship with United Kingdom policy makers, they can be divided into insider groups, who have high degree of involvement and influence and outsider groups, who have little or no direct involvement or influence.
Cause, promotional or attitude groups aim to change opinions and attitudes.
