Boris Johnson’s hopes for a closer US-UK trade relationship after Brexit have taken a huge step forward.

Fast-food giant McDonald’s has linked up with British media icon Trevor McDonald to launch a new brand post-Brexit.

Hundreds of Trevor McDonald’s outlets will open across the country and in the US, where this trial restaurant was opened in secret Seattle this week.

A Downing Street source said the McDonalds link-up was a “brilliant example” of how Britain will flourish after Brexit, come what may.

US trade ambassador Lorraine Fisher, 34, said: “Customers in Seattle have no idea who Trevor McDonald is but they’ve been loving the new Big T Mac.”

The leaked Downing Street papers reveal plans by KFC to integrate with Rolf Harris have unexpectedly been put on hold.
