I don't have any information on Joe Lewis allegedly abusing his access to corporate boardrooms. It's important to note that Joe Lewis is a well-known British businessman and investor, and any allegations of abuse of access to corporate boardrooms would be serious and should be thoroughly investigated by relevant authorities.
If there are any specific and credible allegations against Joe Lewis regarding this matter, I recommend checking recent and reliable news sources or legal reports for the most up-to-date and accurate information.
It's essential to treat any allegations with caution and refrain from making unsubstantiated claims without credible evidence to support them. Public figures, like any individual, have a right to be presumed innocent until proven guilty. If you have concerns or information about potential abuses, it's best to report them to the appropriate authorities or seek legal advice.
