White & Case and Covington & Burling have hired senior officials from the U.K. government’s Serious Fraud Office (SFO) as firms continue to bolster their white-collar practices ahead of the introduction of a controversial new Bribery Act this April.

SFO assurance head Charlie Monteith joined White & Case’s London office as counsel on Monday, while Robert Amaee, who led the SFO’s Anti-Corruption and Proceeds of Crime units, joined Covington as of counsel, also on Monday.
