Today, as might have been anticipated, Andrew Rawnsley took as his subject the apparent thawing of relations between Labour and the Lib Dems. The opinion polls suggest that an outright Labour majority in 2015 is by no means assured. So it makes sense for them to leave the option of plan B open this time around. The major news this week was Ed Balls’ concession that it would be possible to work with Nick Clegg, rather than demand his head on a plate as the price of coalition. Others in the Labour party – notably Tom Watson in the New Statesman yesterday – are, however, holding firm to the Clegg’s-head-on-a-plate option.
