We're hearing now from our political editor Beth Rigby on that projection for Labour to be the largest party at the general election but fail to win a majority.
Beth has been discussing this with Labour sources in recent days, who she says would argue they are not trying to gain vote share in safe seats and are instead targeting battlegrounds.
"For their tests it's can they pick up seats in marginal constituencies and the battlegrounds they need for a general election majority," she says.
One source said Labour is on course to win a majority, arguing independents and other small parties won't get 24% of the vote share at a general election.
They have been saying they are "very happy" with how the vote is distributed around the country.
The party has also said it should be taken into account how much better they are expected to do in Scotland with a weakened SNP.
Beth says these elections show the public believes the government is the problem - the question now is whether Labour is the answer.
"When you look at the number of seats lost by the Conservatives and picked up by Labour, this is not a story of straight switching from the Conservatives to Labour," she says.
