The Conservatives are now polling at their highest level since 2017, while support for Labour has also been growing significantly, according to a new survey of voting intentions.

A SavantaComRes poll for The Sunday Telegraph puts the Tories on 41 per cent - the highest level in one of the firm's surveys since the last general election.

Labour remains eight points behind, but has risen to 33 per cent - its highest level since April.

Meanwhile the proportion of voters planning to back the Brexit Party has reached a new low, at 5 per cent, following Nigel Farage's announcement that he would withdraw candidates from seats won by the Conservatives in 2017, to help Boris Johnson deliver Brexit.

The Liberal Democrats' share dropped by two points to 14 per cent during the course of last week.
