ICM/Guardian - CON 44%(+1), LAB 41%(-1), LDEM 8%(+1)

ICM's regular poll for the Guardian today has topline figures of CON 44%(+1), LAB 41%(-1), LDEM 8%(+1). Fieldwork was between Friday and Monday, and changes are from a fortnight ago. Tabs are here.

There was also an Opinium poll for the Observer at the weekend, which had toplines of CON 42%(nc), LAB 40%(+1), LDEM 6%(-1). Fieldwork for that was Tuesday to Thursday, and changes are from February. Tabs are here.

Both polls also asked questions about how political leaders had responded to the poisoning in Salisbury, finding a similar pattern to YouGov last week. ICM found people thought Theresa May had responded well to the Salisbury poisoning by 51% to 22%, and thought Jeremy Corbyn had responded badly by 42% to 23%. Opinium only asked about approval of May's response, but 41% said they approved, 20% disapproved.

Neither the ICM nor Opinium poll has significant changes, so I'd be cautious about concluding that the poisoning has had any impact on political support. Nevertheless, if we look at the longer trend in public support it does look as though there has been a slight improvement in the Conservative position - late last year the polls were typically showing a small Labour lead, in the last couple of months they've averaged out with Labour and Conservative neck-and-neck. Whether that small change really matters is a different matter, we're a long way from a scheduled general election and there are some very big "known unknowns", like Brexit, before we get to one. A couple of points either way at this stage of the Parliament is neither here nor there.
