Brewer InBev says it will file a statement with U.S. regulators seeking to remove the entire board of Anheuser-Busch, turning up the heat in its $46 billion unsolicited bid for its American rival.

It is proposing its own board for Anheuser, which includes Adolphus Busch IV, the uncle of CEO August Busch IV.

InBev said in a statement it would file a preliminary consent solicitation with the Securities and Exchange Commission later Monday.

The maker of Stella Artois claimed its hand has been forced because Anheuser has refused to enter takeover talks.
