Clifford Chance (CC) and White & Case have advised on Russian oil explorer RusPetro’s $250m (£159m) London listing in one of the first premium-level initial public offerings (IPO) on the London Stock Exchange since last summer.

The deal, which comes amid a tough period for equity capital markets (ECM) work, saw White & Case take the lead role for RusPetro, while CC advised the underwriting banks, which included Bank of America Merrill Lynch, Mirabaud Securities and Renaissance Capital.
