Sky Data poll: 78% think the government is doing a bad job on Brexit

British public opinion has shifted sharply against Brexit, according to a new Sky Data poll.

The survey reveals:

:: The government is haemorrhaging trust regarding the Brexit negotiations

:: Two-thirds of the public - including a majority of Leave voters - now think the outcome of Brexit negotiations will be bad for Britain

:: A significant increase in the proportion who think Brexit will negatively affect themselves personally, the economy and the country overall

:: Most people would like to see a referendum asking between the deal suggested by the government, no deal, and remaining in the EU.

More than three-quarters of the British public - 78% - now think the government is doing a bad job negotiating Brexit, up 23 percentage points from when last asked in March this year.

Just 10% think they are doing a good job - down 13 points.

Theresa May's personal approval ratings have similarly taken a substantial hit - 74% are now dissatisfied with her performance as prime minister, up 14 points, while the proportion satisfied is now at 24%, down 17 points.

And asked how good or bad a deal the government will get when Brexit negotiations are complete, two-thirds - 65% - now think they will get a bad deal for Britain - an increase of 15 points - including 51% of Leave voters.

Just 14% think they will get a good deal, down 12 points.

On the impact of Brexit, 42% of Britons now think it will have a negative effect on themselves personally, up eight points; 18% think it will not affect them either way, and 31% think it will be good.

A majority now think that Brexit will be actively bad for the economy (52%) and the country overall (51%), a rise by four points and five points respectively.

One in three think Brexit will be good for the economy (35%), with 9% saying it won't have an impact, while 40% think Brexit will be good for the country, with 5% saying it will have no effect.

The public by 50% to 40% support a referendum asking the public to choose between leaving the EU with the deal suggested by the government, leaving the EU without a deal, and not leaving the EU - 10% answered don't know.

Asked to choose between those options, not leaving the EU would be the preferred option for 48%, with 27% preferring to leave the EU with no deal, and 13% choosing the government deal - 8% say they would not vote, 3% don't know.

Leave voters would prefer no deal to the government deal by 51% to 22%, and Conservative voters would prefer no deal to the government deal by 44% to 21%.

Were a referendum to take place asking for second preferences, in the final round remaining in the EU would have a clear lead over no deal Brexit by 59% to 41%, excluding those answering don't know and those who would not vote.
