Conservatives lead Labour by 11-points in first poll with Theresa May as PM

The Conservative party currently hold an 11-point lead over the Labour in the first YouGov poll released since Theresa May became prime minister.

In a poll carried out over the first full weekend since May announced her cabinet – as well as the ongoing Labour leadership contest – 40% of those asked said they would vote for the Tories if there was an election tomorrow compared to 29% for Labour.

The poll shows a huge swing back towards the Conservatives, who trailed Labour by three points when the same question was asked in April.

YouGov's Matthew Smith said the boost for the Tory party could be a result of a "new leader bounce" – in which sees a trend of parties polling relatively higher in the weeks and months following the appointment of a new leader.

The latest will also make dreadful reading for Jeremy Corbyn, who is currently facing a challenge for the Labour leadership from Owen Smith after frequently ignoring calls to step down by his own MPs.

The data – which also reveals Labour are currently polling behind the Tories in every region of Britain except London – will once again ask the question whether Corbyn could ever be elected prime minister despite appearing to have overwhelming support among Labour members.

Elsewhere, support for Ukip has fallen eight points since last month's poll, which Smith puts down to "an early signal that, having achieved the party's central mission during the Brexit referendum, some of their supporters are now looking elsewhere."
