An 83-year-old farmer who kept Britain’s ‘most dangerous’ herd of cows ignored official warnings to control them before they attacked and killed a retired professor.

Brian Godwin was ordered to pay £30,000 after failing to install electric fencing before Mike Porter, 66, was trampled to death as he walked across a footpath.

A court heard that Godwin’s herd had attacked ramblers on at least four previous occasions before the fatal stampede, including a dog walker who suffered a broken neck.
