Commentary on March 2021

Posted 4 Apr 2021

Our March monthly poll-of-polls shows the Conservatives gaining ground slightly on Labour. Taking an average over nine pollsters, the Conservative lead is now 6pc, up from 5pc the month before. But that single number is just an average of some disparate individual polls, which run from a modest 2pc lead (BMG) up to a chunky 10pc lead (YouGov). The full breakdown is here.

If there were an imminent general election, the Conservatives could expect to be re-elected with a working majority of around 32 seats. They appear to be benefiting from the covid vaccination programme and the gradual unwinding of lockdown.
