From Opinium, based on responses from 5th May:

To what extent do you approve or disapprove of …The way Nicola Sturgeon is handling her job as Leader of the SNP:

  • Con 22% (20%)
  • Lab 52% (46%)
  • Lib Dem 55% (56%)
  • SNP 86% (83%)

In brackets above, the results of a similar poll also by Opinium, on 26th March, suggest increasing support.

In sharp contrast, Boris Johnson’s performance was only approved of by 17%, 34% and 14% of Lab, Lib Dem and SNP supporters and this represents a fall from 20%, 39% and 14% in March.
