I found the phrase 'In the light of the nature of the allegations' in a BBC news article titled 'Jeff Bezos: Amazon boss accuses National Enquirer of blackmail'.
The context is:
"American Media believes fervently that it acted lawfully in the reporting of the story of Mr Bezos. Further, at the time of the recent allegations made by Mr Bezos, it was in good faith negotiations to resolve all matters with him," the company said in a statement.
"Nonetheless, in light of the nature of the allegations published by Mr Bezos, the Board has convened and determined that it should promptly and thoroughly investigate the claims. Upon completion of that investigation, the Board will take whatever appropriate action is necessary."
I don't understand exactly the meaning of 'the nature of the allegations'. Does it mean 'the intention of allegations'? Do they mean the fact that they were in a good relationship but Mr Bezos broke that by the allegations?
