How tragic is this story, what must the poor mother be going through :(
Andrew Hopper had taken the woman out for a day trip to the seaside, along with his daughter, Rebecca, and son Lewis, eight months.
As he turned to embrace her, he let go of the buggy and a gust of wind blew it over the promenade at Warren Apron in Folkstone, Kent, with the children still strapped in.
Both Mr Hopper and his mistress leapt into the water when they realised what had happened and managed to unclip them.
But then they got into trouble themselves, and six passers-by had to rescue the children, who were both unconscious and face-down in the water.
Rebecca was airlifted to a specialist unit at The Royal London Hospital in Whitechapel, but was declared dead two hours later. Lewis was taken to the William Harvey Hospital in Ashford, where he is still recovering.
Their mother, Mr Hopper's wife Sarah, 35, had been completely unaware of her husband's affair until the tragedy happened.
