Labour may or may not be about to replace Keir Starmer with Andy Burnham. The major reason they're considering this because they hope it'll improve their chances in the next election. This is a "Decision Market", in which you can bet on labour to win in either case - in principle, this could help Labour make that big decision!

Here's how it works. Suppose for a moment that Burnham becomes labour leader. Then there will be refunds for everyone who bet Assuming Starmer is Labour leader - whether they bet labour wins or they bet labour loses. They are refunded because, well, I guess we will never know what would have happened. But we WILL get an answer for the one that assumes Burnham is leader - so that market continues as if it was an ordinary market where you can buy and sell bets all the way up to the next election.

Labour may instead stick with Starmer. In that case, we refund the people who bet either way on the Assuming Burnham market. Starmer market continues like usual.

You can count on me to resolve this market within a few days of the results of the next general election :) this market works exactly like a previous market of mine:

Conditional upon the Democratic party replacing Joe Biden as nominee, will they win the election?‌

Be aware that this is a market on labour *getting a majority of seats in the house of commons*. Yes, they may fall short of a majority but still be the largest party; or they may be a party that is in a coalition. Those are two ways the leader of the labour party (Starmer/Burnham) is the Prime Minister - but in both of those situations, that means labour did not get a majority so the market resolves no. The main reason for my setting it up this way is that Burnham advocates put him forward based on the expectation that labour could get a majority (it's also for the sake of simplicity - at the end of the day, coalitions and minority governments are nerd stuff, as is the popular vote).

I will not bet on this market.
