No shortage of articles about this, and nearly 100% rubbish.

But masses of priceless free publicity for Betfair.

But while wading through the latest I stumbled on this Betfair bombshell.

Unfortunately it is scant on detail.

The article calls Betfair SP the last price matched, which is obviously rife for manipulation.

Who will be the counterparty to Betfair SP? Customers as SP layers, or Betfair?
