This week Ed Miliband's personal ratings rose above David Cameron for the first time.
The Survation poll for the Daily Mirror gave the Labour leader an overall rating (the difference between people who think he's doing a good job and those who think he's doing a bad job) of +3.2 points, compared to +2.3 for the prime minister.
What's significant is that the poll arrived in a week when the Tories stepped up their negative campaigning against Miliband, led by defence secretary Michael Fallon claiming the leader of the opposition would "stab the United Kingdom in the back" just like he had "stabbed his own brother in the back".
Senior Tory MP Nick Boles meanwhile claimed that Russian president Vladimir Putin would welcome a Labour victory...
... which led to widespread ridicule.
Miliband described Fallon as a "decent man" but said he had "demeaned himself and he's demeaned his office". "National security is too important to play politics with," he added.
