London's Euronext.liffe is set to launch options on shares in Mittal Steel, the steelmaker that recently agreed a merger with Luxembourg peer Arcelor, as the derivatives exchange looks to take advantage of increasing liquidity in its over-the-counter offerings.

Euronext.liffe said it intends to launch equity options in Mittal, which will each represent 100 shares in Mittal and be available for trading from September 11.
