Chris Heaton Harris has been campaigning in the general election
The Transport Minister has promised to improve security at Ports like Grimsby and Immingham following the discovery of 39 people found dead in a refrigerated lorry last month.
Eleven arrests have been made in two provinces in Vietnam.
But now fears have risen that similiar events could happen at Grismby or Immingham.
Transport minister Chris Heaton-Harris was campaigning in Lincoln yesterday, he believes security at ports is improving and has pledged to do more if the Conservatives are elected.
