trust £800k pound on the whim of a Scotsman? yeah, nah;)

When news reports it's close, it motivates voters to take action. So those that thought I won't bother, will turn out to make sure it doesn't go ahead.
In fact news reports like this, turn the odds further in your favour.

Does anyone know if there are there a lot of these political type bets per year or are there only a few that betfair bet on? i.e. Is it worth adding to your arsenal?

Betfair bet on quite a few, but I wouldn't be taking odds about foreign countries other than UK USA and AUS.
There are also State elections etc. But truthfully I don't know that these are markets you want to get into.

Never in doubt despite "too close to call" statements on the news.

Don't bet on political events but this result was a certainty.
What fool would vote himself out of a welfare $$?

Which is going to be the eventual end of democracy, when too many ppl can decide the outcome by voting to receive an income from the public purse for doing nothing.
Eventually the leeches outnumber the providers and the system collapses.

ooo there we have it.

Already self destructing here blackdog, and it's going to get to implosion within the next few years!
Less jobs
Less housing
More violence
More retirees that are pension reliant.

I wonder if Betfair would run a market on economic collapse?

I suggest that the large bet was probably to cover a business loss which would have eventuated for the person concerned if the YES vote had succeeded. Very astute, if that is the case.
