For Trump-watchers, there’s a strange feeling of déjà vu to the U.S. president’s arrival in London for a three-day state visit. Just like his previous U.K. trip last summer, there have already been catty attacks on London Mayor Sadiq Khan, displays of uncomfortable civility from representatives of the U.K. government, and lots of mass demonstrations planned for this week. Protesters are pumping up the Trump baby blimp for another round of public appearances, while the usual round of artistic interventions is joined this year by a giant grass penis etched in the fields next to the runway where Trump landed. The “carnival of resistance” is coming back to town.
