In a statement released this morning, Ed Miliband said:
“I want to send my warmest congratulations to the Duke and Duchess of Cambridge.
“I wish them and their new baby boy all the health and happiness in the world.
“I know people right across Britain will be absolutely delighted for them.
“The moment your baby has just been born is a very special time. I hope William and Kate get time together as a family to enjoy it because that’s something you never forget.”
