       Friends and family joined a procession through the youngsters' hometown of Tredegar, south east Wales - one dressed as Spiderman and another as Elsa from Frozen.

       Gracie-Ann's coffin was painted blue and covered in white snowflakes to reflect her love of the Disney hit, while Jayden-Lee's was red and blue and appeared like the Marvel superhero's web.

       After leaving the family home, the carriages carrying the children passed by their school before arriving at St George's Church.

       Crowds of mourners then piled inside for an emotional service.

       The order of service read: "Forever missed but never forgotten.

       "You both left us beautiful memories. Your love is still our guide.

       "And although we cannot see you, you are always by our side."
