UK: Metro mayors polling
Opinium conducted polls of the West Midlands and Tees Valley metro mayoral elections for the Northern Powerhouse Partnership.
Date for these can be found below
NOTES:
West Midlands based on a total sample size of 971 and 357 once this is filtered to the voting intention question headline figures.
Tees Valley was commissioned on a ‘best efforts’ basis and has a total sample size of 387 and a base of 243 for the final headline voting intention question. No turnout filter was employed here as this would render the sample size unreasonably low for reporting.
