Tom Karen, designer of Raleigh Chopper and Marble Run, dies aged 96

Family and friends pay tribute to Karen, who also oversaw design of Reliant Scimitar GTE car

Tom Karen, the British designer behind the Raleigh Chopper and Marble Run has died aged 96, his family have confirmed.

His daughter Eugenie told the Guardian: It was a privilege to have been close to such a creative person. He made things constantly and even his most throwaway creations were things to be treasured. I have a paper Spitfire that he casually made for my sons in minutes, but it captures the aircraft's character perfectly.
