Sorrell hits CES to plug S4 – and push aside WPP exit

If there’s a big pow-wow going Sir Martin Sorrell will be there (CES this week, Davos to come – for all we know he’ll be providing the Super Bowl half-time entertainment.)

Here he is with CNBC’s Julia Boorstin who’s gamely trying to ask him what went on at WPP and, in the light of that, why investors are ploughing money into his new venture S4 Capital.

But SMS isn’t having any of that.

He’s also remarkably nice about Facebook – is a deal afoot?
