Valence shell electron pair repulsion theory
So I get that lone pair repulsion causes the bonding pairs to be pushed more close together which reduces the bond angle. But the final sentence says lone pair lone pair angles are the biggest but if you look at the diagram the biggest angle is where there is no lone pair so I'm confused?

What it means by that is that the angle between two lone pairs is the biggest angle you will get when you have a molecule with at least 2 lone pairs and at least 2 bonding pairs.
The angle between two bonding pairs will be smaller, since bonding pairs are less repulsive than lone pairs.
