It has been a chilly few days with temperatures averaging around 0°C, by far the coldest it has been all winter. But with clear blue skies and a bright sun, the weather has also been its crisp, bright best.
These photos show the cold weather making London shine and shiver at the same time. Happy days for purveyors of furry hats; tough times for traders working outdoors.
The cold front is due to hang around a little while longer with some snow showers forecast for the weekend.
