BRUSSELS (Reuters) - U.S. chipmaker Broadcom is seeking European Union antitrust approval for its $61 billion bid for cloud computing company VMware, Broadcom said on Tuesday in a statement. "We are confident that this deal does not present any competition issues and look forward to working with the European Commission throughout this process", the company said. The EU competition watchdog will decide by Nov. 20 whether to clear the deal. It can open a four-month investigation if it has serious concerns.
