From the Brexit betting market:

73% of the total money being wagered is on "Remain"...

BUT-- over 70% of all individual bets have been for "Leave"...

That tallies with the view that all the establishment fat cats favour staying in the EU, while the general public favour out. The number of individuals favours Leave.

The rich elites trying to skew the odds to give the impression that "remain" is the inevitable result?

>> While the high-rollers fancy "Remain", the smaller money clients are overwhelmingly backing "Leave"...
