Free traders and farm groups testified Tuesday that they hope the U.K. will be freed from what they regard as overly zealous regulations for agriculture under the European Union when Britain leaves the bloc on March 29, Pro Trade's Doug Palmer writes. Those include barriers on genetically modified crops, chlorine-washed poultry and use of artificial growth hormones in beef production.

On the other hand: If the U.K. remains part of the EU's customs union or maintains European regulatory standards, "it will be difficult or impossible to get the kind of agreement that would provide benefits to U.S. agriculture or the U.S. pork industry," said former U.S. agricultural trade negotiator Craig Thorn on behalf of the National Pork Producers Council.

Brexit update: British parliament rejected a proposal to delay the March 29 deadline, but MPs did vote for Prime Minister Theresa May to renegotiate a Brexit deal with the EU. Brussels immediately squashed that possibility, POLITICO Europe's Charlie Cooper and David M. Herszenhorn report.
