PMQs live: Sunak facing Starmer at PMQs as Tory MP defects to Labour

Sunak says since he became prime minister small boat crossings "are down by a third".

"When it comes to border control, there's a crucial difference between us. We want secure borders, he is happy with open borders," Sunak says.
