seen advancing on kyiv is much longer than earlier thought. the uk has asked its ports to block access to all russian—flagged, registered or owned ships. in a further ratcheting up of sanctions, the uk's transport secretary grant shapps wrote to the country's port operators, telling them the government will try to pass legislation prohibiting their arrival. russian vessels are regularly used to transport oil and gas to the uk, so denying them access is likely to have an impact on the country's economy. joining me now is peter aylott, director of policy at the uk chamber of shipping. good morning to you. did you get a call from government yesterday about this? good mornin: yesterday about this? good morning and _ yesterday about this? good morning and thank- yesterday about this? good morning and thank you. - yesterday about this? good morning and thank you. we yesterday about this? good - morning and thank you. we did not get a direct call, we got a letter. the letter itself was an ask, as you quite rightly say. it has not yet been legalised, which creates a bit of a problem as these emergent issues always do, in the sense our ports are open for vessels.
