In terms of their Ipsos MORI leader satisfactions ratings TMay and Corbyn are now the most unpopular PM and opposition leader duo of all time with an aggregate net negative of -96. They beat the 1981 Thatcher/Foot negative of -89

The Ipsos-MORI leader satisfaction ratings have been carried out in the same manner since the 1970s with the question being put in the same way over the decades. It is the longest lasting series of leader ratings in British politics and we can make historical comparisons.
Normally when one of the opposition leader or PM is up the other one is down. So the current trend of both Corbyn and TMay having terrible figures is something of a rarity and the current numbers say something about post Referendum UK politics. That narrow victory for LEAVE three years ago has changed so much.
As as I have pointed out many times the historical record is that leader ratings are a much better guide to electoral outcomes than standard voting intention polls. Given that the Tories are changing their leader this summer then it can be expected that the new person will get something of a boost whoever wins the leadership contest. At the very minimum they will have the advantage of not being Theresa May.
The same is not the same for the Labour because whatever happens it appears Corbyn seems absolutely rock solid in his position of leader. That he is proving to be electorally toxic doesn’t seem to bother the party and it is likely that it will lose another parliamentary by-election next week.
Normally opposition parties proper in parliamentary by-election while governments struggle. In fact Corbyn was two years ago the first Labour leader since 1982 to suffer the loss of a seat while the party was in opposition.
But he ain’t going anywhere.
