With both main parties neck and neck as things stand, a hung parliament looks very much to be on the cards and with no overall control expected, the nature of the resultant coalition remains anyone's guess.
As such, it could take some time before any punters who have had a wager on the next government receives any winnings and if no party wins a majority, it will be up to the current Prime Minister to form a coalition or else resign prior to the first sitting of the new parliament on 18th May.
Nevertheless, other political parties can also hold talks concerning alliances as happened in the last election five years ago. Any new government needs to get parliament to pass the forthcoming Queen's speech prior to 27th May, however bookies' rules are far from clear as to whether or not their 'Next Government' markets would be settled following the announcement of a coalition or following the approval of the Queen's speech.
It took some five days before a coalition was agreed in the 2010 election and it remains extremely unclear as to what will happen this time around. We are entering scenarios which haven't occurred previously and there are some constitutional issues which will rear their heads once the votes have been counted.
The polls will open tomorrow, however don't expect any bets to be paid out anytime soon, it could get messy!
