Derbyshire will be colder than Moscow overnight, according to weather experts.
The Met Office is forecasting a widespread frost across the county Sunday night into Monday, with temperatures expected to plunge to freezing.
In Moscow, meanwhile, overnight temperatures will only fall to lows of 6C, the Met Office said.
The freeze comes after a weekend which saw temperatures crashing down following an unseasonably warm week.
However, warmer weather is expected to return in the coming days.
