Diane Abbott failing miserably to answer Piers Morgan's straight question re illegal immigration

Watch the video and at 0:23 and 2:01 you can almost hear Diane Abbott's brain trying to get into first gear. It's a sound you can hear again and again when Diane Abbott is asked a question any more challenging than what's 2 plus 2. It's unbelievable that this woman has such a senior shadow cabinet role and could one day be Home Secretary.
