Top traded markets of all time??

India v Australia 2nd test going into day 4 is about to hit £44 million. I can't remember if a test has ever hit these levels before???

I know Politics is getting large sums done these days and tennis Grand Slams hit £50 mill plus but do any of you have any figures of say the top 50 markets ever traded on BF since day dot.

From what I remember last years U.S election tops the lot on about £200 million followed by the Referendum on around £117 million.
