Visitors' books from Downing Street signed by some of the most famous figures in recent history have been made public for the first time.
World leaders and members of the Royal Family are among the names in the three red leather, gilt-tooled volumes being released by the National Archives, spanning 1970 to 2003.
The names of visitors to No 10 are not made public so the books provide a valuable record of who had private conversations with prime ministers.
One of the volumes was offered for sale earlier this year by a London auction house who said it had been rescued from a waterlogged basement by a former civil servant, but the government blocked the sale saying it was Crown property.
