Добрый день!

Подскажите, пожалуйста, как можно перевести "a Westminster reporters’ lunch" в следующем тексте:

Matt Hancock, the culture secretary, sought to blame EU regulations on procurement. He told a Westminster reporters’ lunch: “There is an irony, which is these rules are European rules and we are going to be leaving the European Union and then we may be able to – if we choose to – set out our own procurement rules.”
