About Cambridge Clarion

Clarion provides independent, non-profit reporting and information from England for the benefit of good people everywhere The emphasis is on independent original reporting or observation over analysis or opinion.

By policy and in fact, this website does not use any javascript. It is a non-commercial website which does not carry advertisements and does not attempt to make a financial return in any way.

Clarion started in 2001 as a group of friends in Cambridge opposed to British involvement in bombing Afghanistan and the proposed war of aggression against Iraq in 2003, but it no longer campaigns or presents any editorial position. It is now maintained by Stephen Hewitt.
