Brits have been warned to brace for a plague of rats this winter as hunters report catching rodents more than 20 inches long.

A 'horrendous' infestation is underway following a period of hot summer weather and fast food waste that has created optimal conditions for vermin to thrive.

The founder of the Yorkshire Rat Pack, Kieran Sampler, said his group was now catching huge rats and warned of 'horrendous' times ahead.

Mr Sampler, who hunts rats in the traditional way with two Lakeland terriers, told The Telegraph: 'It is going to be a bad winter for rats, and people don’t realise – it is going to be horrendous.

'There is always going to be a bad winter after a good summer.'
