Centrebet and sportingbet moved in lock step around mid-day yesterday, on the back of a 54-46 Newspoll.

Both sites took their Australian Federal betting markets down last night just after 7pm, when the news re Peter Slipper’s resignation broke. They’re yet to come back up. You’ve got to conclude that they’re worried about being clobbered by insiders when things are swirling in Canberra. Thumbnail below is clickable.

Sportsbet’s Labor price eased out to $3.25 from $3.00 (Coalition $1.33 in to $1.28) between 9 and 10 this morning, but they stayed up overnight.

Implied probability of a Labor win is about 25% at the last Centrebet prices ($3.72 to $1.27).
