Demand for Carrie Johnson’s backless fuchsia dress crashes designer’s website

Prime minister's wife embraced spotlight for Boris Johnson's leaving speech and visit to Balmoral

Throughout her three years as the prime minister's partner, Carrie Johnson has had to make many fashion choices. Today, as she left No 10 alongside Boris Johnson for the last time, it was no different. However, the end result was certainly unexpected.

For the occasion she wore a fuchsia pink maxidress from the British brand Harmur. Described as a dreamy maxidress", it features a ruched waist, billowing sleeves and a cut-out back - a design signature of the brand. No sexier way to walk away," reads a tagline for Harmur. Was this Carrie having the last laugh as she plotted what to wear to watch her husband leave his position of political power?
