'Why are you doing this to me?' Defendant led away from dockpublished at 12:21 BST
The prosecution has now finished asking Kate McCann questions.
The judge was about to instruct a 10-minute break before she is cross-examined.
But at the conclusion of Mrs McCann's evidence, Julia Wandelt began to sob loudly and shouted: "Why are you doing this to me?"
She was then led away by two dock officers, leaving Karen Spragg alone.
