What's next for Mike Baird?

He posted a congratulatory message to incoming Premier Gladys Berejiklian on Facebook, moments after she was elected as his replacement unopposed by the Liberal party room.

There was no accompanying tweet, however. Mr Baird deleted his Twitter account on Monday after saying his resignation would be a chance for more time with his family and less on social media, with which he has had an ambivalent relationship.

But after he walked a couple of hundred metres down Macquarie Street on Monday afternoon to hand in his resignation as premier, Mr Baird is free to focus on life after politics.
