In the UK the term is defined by the government as anyone who is deemed by the government a threat to the government or the people or someone’s property or the predominant local religion. But recently it’s been exclusively used for the first one. In this country state law is valued higher than corporate, moral, ethical and religious laws, so YMMV

Introduction
The Terrorism Act 2006 uses the definition of terrorism contained in the Terrorism Act 2000. Section 34 amends that definition slightly, to include specific types of actions against international governmental organisations, such as the UN. The definition in the Terrorism Act 2000 (as amended) states:

1. (1) In this Act “terrorism” means the use or threat of action where:
2. the action falls within subsection (2)
3. the use or threat is designed to influence the government or an international governmental organisation or to intimidate the public or a section of the public
4. the use or threat is made for the purpose of advancing a political, religious or ideological cause.  

(2) Action falls within this subsection if it:

1. involves serious violence against a person
2. involves serious damage to property
3. endangers a person’s life, other than that of the person committing the action
4. creates a serious risk to the health or safety of the public or a section of the public
5. is designed seriously to interfere with or seriously to disrupt an electronic system

Section 1(3) to (5) goes on to expand on the effect and extent of this definition.
