The youngest MP in the house is David Lammy, the Labour member for Tottenham in North London. He's about 27-29 years old.
He's bright, an inner-city success story, (a difficult upbringing in a rough area who became a successful lawyer).
He also seems to have showbiz friends, like Alicia Keys, at least one TV personality has also been in a relationship with him.
He invited Alicia Keys to play the concert, apparently he's concerned that many younger voters are put off by Parliament, and of course it's publicity for him too!
He's one of the few Black MP's in the house, and is being tipped as a rising star.
