UK prime minister Boris Johnson has been out and about for London International Shipping Week.

He visited the lighthouse tender NLV Pharos in the Thames and somehow became involved with school children and a model of a Maersk containership.

Is he conjuring a solution to trade problems after Brexit? Or does he think a fleet of miniaturised vessels could solve the emissions question?

We need TradeWinds readers to come up with an amusing (yet printable) caption for this odd photo.
