The governing body of boxing has provisionally suspended the Amateur Boxing Association of England and asked its disciplinary panel to review the case.
Governing body AIBA says it "could not tolerate the serious violations committed." AIBA did not specify details.
The suspension bars English boxers, coaches and officials from competitions six weeks before the junior world championships in Ukraine. The senior worlds will be held Oct. 11-27 in Kazakhstan.
AIBA was already investigating "political conflicts" involving England and its other British member federations.
This month, AIBA withdrew the British Lionhearts franchise from its World Series of Boxing professional competition.
AIBA says it also suspended the Cameroon federation in a separate case and requested new elections there within three months.
