Two nationwide opinion polls have been published in the past 24 hours, both of which show Labour maintaining a large lead over the Conservatives.

A poll by Verian, carried out online from Friday June 7 to Monday June 10 among 1,305 adults in Britain, gives Labour a lead over the Tories of 21 percentage points.

The figures are Labour 41%, Conservative 20%, Reform 15%, Liberal Democrats 11%, Green 8%, SNP 3%, Plaid Cymru 1% and other parties 1%.

A more recent poll by Norstat, carried out online from Monday June 10 to Wednesday June 12 among 1,017 adults in Britain, puts Labour 20 points ahead of the Tories.

The figures are Labour 41%, Conservative 21%, Reform 17%, Lib Dems 11%, Green 6%, SNP 3%, Plaid Cymru 1% and other parties 1%.

An average of all polls that were carried out wholly or partly during the seven days to June 13 puts Labour on 43%, 21 points ahead of the Conservatives on 22%, followed by Reform on 14%, the Lib Dems on 10% and the Greens on 6%.

Reform’s average is up one percentage point on the figure for the previous week while the Tories are down one point, with the averages for the seven days to June 6 being Labour 43%, Conservative 23%, Reform 13%, Lib Dems 10% and Green 6%.

On May 22, the day Rishi Sunak called the General Election, the seven-day averages stood at Labour 45%, Conservatives 23%, Reform 11%, Lib Dems 9% and Green 6%.

The averages have been calculated by the PA news agency and are based on polls published by BMG, Deltapoll, Find Out Now, Focaldata, Ipsos, JL Partners, More in Common, Norstat, Opinium, People Polling, Redfield Wilton, Savanta, Survation, TechneUK, Verian, WeThink, Whitestone and YouGov.
