Belgian police and German investigators carried out a raid on Tuesday at the headquarters of the centre-right European People's Party (EPP) as part of an investigation in Germany.

The party, which has the most members in the European Parliament, said in a statement that representatives of authorities from Belgian and Germany had visited its headquarters in Brussels on Tuesday.

While the exact reason for the raid has not been officially disclosed, it is believed to be related to an ongoing investigation in the German state of Thuringia. The EPP statement did not provide any further information on the nature of the investigation or the specific allegations being investigated.

The EPP has a broad political presence across the 27 European Union (EU) member states, as well as in other countries such as the western Balkans, Norway, Switzerland, and Ukraine. It is the largest and most influential group in the European Parliament, with a membership that includes prominent centre-right parties from across Europe.

The party has stated that it is cooperating fully with the authorities involved in the investigation, providing all relevant information and documentation. The EPP has also emphasized that it is committed to maintaining the highest standards of transparency and accountability.

The raid on the EPP headquarters has raised concerns about the potential impact on the party's political influence within the EU. The EPP has been a dominant force in European politics for decades, and its members have held some of the most important positions in the European Commission and other EU institutions.

However, the EPP has also faced criticism in recent years over allegations of corruption and other forms of misconduct. In 2019, the party was embroiled in a scandal involving allegations of illegal lobbying and conflicts of interest, which led to calls for greater transparency and accountability.

The EPP has since taken steps to address these concerns, including adopting a new code of conduct for its members and introducing more rigorous oversight mechanisms. However, the raid on its headquarters suggests that there may still be concerns about the party's conduct, particularly in relation to its activities in Germany.

The investigation in Thuringia is likely to be closely watched by political observers across Europe, given the EPP's prominent position in European politics. It remains to be seen what the outcome of the investigation will be, and whether any charges will be brought against the EPP or its members.

In the meantime, the party has stated that it will continue to cooperate fully with the authorities involved in the investigation, and will do everything in its power to ensure that its activities are fully transparent and accountable. The EPP has emphasized that it remains committed to its values of democracy, freedom, and the rule of law, and will continue to work towards a stronger and more united Europe.
