In our report ‘In Whose Interest?’, Transparency International UK has looked at how some parliamentarians are engaging in activity that appears to be supporting or legitimating the actions of corrupt and repressive regimes in Azerbaijan, Russia and Bahrain. Although these case studies reflect a range of engagement – from potentially unknowing legitimation through to seemingly active endorsement – the effect of these activities is to provide a veneer of respectability to foreign regimes that stymie freedom of expression, ride roughshod over the rule of law and abuse their positions of power for personal enrichment.
