Conservative 42% (no change)
Labour 36% (down 2%)
Lib Dem 13% (up 1%)
Whilst the Lib Dems are up from their recent low of 12% and Labour down a shade, the changes are within the margins of error. The daily YouGov polls seem to have settled into a pretty steady state at the moment with the Conservatives riding high over 40%.
Changes shown are compared to the last YouGov poll I reported on 31 July.
