Wachtell Lipton Rosen & Katz has been drawn into the controversy over the $187.5m (£103m) pay package of former New York Stock Exchange (NYSE) boss Richard Grasso.

In a lawsuit filed last week (24 May) by New York Attorney General Eliot Spitzer, both Grasso and former NYSE compensation committee chairman Kenneth Lan-gone are being sued for violations of New York corporation law.
