which of the following developments has caused recent controversy between poorer and richer members of the european union

One of the developments that has caused recent controversy between poorer and richer members of the European Union is the proposed allocation of EU funds for the recovery from the COVID-19 pandemic. poorer member states have argued for more financial support from richer members to help them recover from the economic impacts of the pandemic, while richer member states have been reluctant to provide additional funding. This has led to tensions and debates within the EU about how to distribute funds and support among member states.
