MEPs who signed a controversial 2021 letter on EU 5G policy linked to a corruption probe involving Huawei denied receiving payments or inducements. The Belgian Public Prosecutor's office charged five individuals with corruption and money laundering related to the case. The letter criticized EU policies that excluded foreign vendors from 5G networks, and its signatories, including some who are no longer MEPs, defended their actions, stating they were motivated by the need for broadband access. Transparency International flagged the letter in 2021, but the European Anti-Fraud Office chose not to investigate further.
