<P> The UNCRC defines children , for the purposes of the Convention , as persons under the age 18 , unless domestic legislation provides otherwise . In that spirit , this timeline includes as children all those below the UK age of majority , which was 21 until 1970 when it was reduced to 18 . Although the Crown Dependencies of the Isle of Man , Guernsey and Jersey are not constitutionally part of the UK , the British government is responsible for their external affairs and therefore for their international treaty obligations , so this timeline includes references to matters in those dependencies . </P>
