Carl Icahn on Friday alleged that Illumina's directors demanded extra personal liability insurance before the biotech company signed off on a $7.1 billion acquisition of cancer test developer Grail in 2021. 

The claim is the latest development in a brewing proxy fight between the activist investor and San Diego-based Illumina, who have been trading jabs over the Grail deal that faces scrutiny from European antitrust regulators. Icahn, who owns a 1.4% stake in Illumina, is pushing for board seats at the DNA sequencing company.
