Church leaders have written to MPs and MEPs calling for concerted action from all political parties to address the issue of tax justice.

Churches across Britain are marking a national week of action by speaking out against the social exclusion of people who are poor or homeless.

Charities, church groups and trade unions have combined to call on the government to stop punishing the poorest through its economic and welfare policies.

Large numbers of people will switch off Facebook on Saturday in protest at the company’s tax avoidance. The action has been launched by Church Action on Poverty.
