World Press Freedom Day
May 3 was World Press Freedom Day, established by the UN's General Assembly 17 years ago to highlight violations of the right to freedom of expression, and to serve as a reminder that many journalists risk death or jail in attempting to exercise that right.
Freedom of expression is recognised in international law and guaranteed in many national constitutions, but too many governments make it a right that is impossible to exercise.
Each year more than 2,000 people fleeing persecution are referred for help to the MF. Their numbers include journalists, writers, students and political campaigners who have fallen foul of the authorities at home for attempting to express their views openly.
Here, journalists and artists from the UK speak out in defence of free speech while MF clients recount how they were treated for voicing their opinions.
