What if, following the 2010 hung parliament result, Labour had formed a coalition government with the Liberal Democrats? This would require a 'rainbow coalition' to reach an overall majority. With Sinn Fein abstentions, 323 or maybe even slightly lower(after the Speaker and Deputy Speaker) would make up an effective majority in the House. Labour+LibDem=315 seats. Then add on Plaid Cymru, which could probably get the 300 million pounds for Wales as the DUP did with Theresa May IOTL, so 318 seats, plus the SDLP, Sylvia Hermon and the Greens for 323 seats, and 329 with the SNP's 6 seat MPs. Together, the government has an 8-seat majority.
How could such a deal come together? It seemed to be close in the OTL 2010 negotiations, however there were serious obstacles to a deal, and it was unclear how seriously either one took the prospect. Gordon Brown would have resigned, and IMO Alan Johnson would have become PM(https://www.theguardian.com/politics/2013/apr/28/alan-johnson-prime-minister-almost), and could have been a unifying figure for the coalition. The future of electoral reform seems unclear, as the LibDem demand of AV without a referendum never seemed palatable, though Labour did propose adding a question on PR to the referendum. How would this government have handled the economy? Some austerity was probably inevitable, but likely the Labour-LibDem cuts would be less than the Tory-LibDem cuts. What would happen to David Cameron, having failed to win an overall majority or form a government? Could he hang on, having gained nearly 100 seats, or would he lose the Tory leadership, and if so who would replace him? How long would this government last? What would be the outcome of the next UK election? What if?
