Icahn may muscle in on Yahoo board

Internet firm Yahoo, which earlier this month drove away a $47.5 billion (£24.4 billion) bid from Microsoft, may now face an assault by billionaire investor Carl Icahn.

He is considering a battle to force himself on to Yahoo's board, and last week built a "significant" position in Yahoo of up to 50 million shares, say reports in New York.

Any takeover of the board by Icahn is likely to put the Microsoft bid back on the agenda.

Icahn is said to be considering whether to nominate a full or partial slate of directors.

Investment firm Firebrand is also reportedly considering a board fight with Yahoo.
