Should we declare a National Kindness Day to remember Princess Diana? A campaign by the Duke of Cambridge and Prince Harry's mother by the Diana Award, aims to inspire 20,000 acts of kindness throughout 2017.

The Princess, who was born at Sandringham, died in a car crash in Paris on August 31, 1997 when William was 15 and Harry was 12.

Research by the Diana Award found that just over half of us had experienced a random act of kindness by a stranger over the last year.

Some 34pc were given a compliment, 20pc have been given directions and 10pc received an offer to pay for their food or drink.

Tessy Ojo, chief executive of the Diana Award, said: 'It's heartening to see that as a nation we're kind and caring, but these new statistics also highlight there's much more we can do to make us even kinder. That's why we're kick-starting a campaign of kindness on National Kindness Day in memory of Princess Diana.'
