Looks like Ed Miliband's performance in the not-a-debate on Thursday has worked for Labour. Tomorrow they've moved ahead in a YouGov to outside the margin of error for the first time in a while. Close to majority territory even with the SNP causing them problems:

The other thing is that even with the SNP doing so well they will side with Labour and before this poll a Tory/LibDem coalition doesn't have the numbers to form a majority Government.
At this rate it's looking likely it will either be a small Labour majority or Labour propped up by the SNP on a vote by vote basis.
