to truly represent the full diversity of its population in the Parliament.

Although this election brought a welcome increase in the numbers of racial and ethnic minorities elected, Brexit will roll back most of the gains.

The United Kingdom elected the most POC ["people of color"] MEPs, and when they leave in October, it will greatly reduce racial representation in the European Parliament. After Brexit, not only will there be seven less MEPs of colour, but there is a risk that commitment to equality and diversity principles such as equality data collection, positive action, and even the acknowledgement of racism as a major issue, is likely to falter.

We also see that minorities are not a monolith and the elected ethnic minority MEPs represent a range of political stances. Far-right parties such as Le Pen's Rassemblement National and the UK's Brexit party will send one MEP each to the European Parliament, and Belgium's New Flemish Alliance (N-VA) - known for its strong opposition to the UN's migration pact - elected Belgium's only MEP of colour, Assita Kanko.
