Just over 18 months ago, in a heavily publicised speech at Lancaster House, the Prime Minister insisted that she was confident that Britain would get a ‘good deal’ from the Brexit negotiations. She has repeated that claim many a time since.

But as the latest instalment of a two-year National Centre for Social Research study of public attitudes towards the Brexit process reveals today, voters have become increasingly doubtful that the Prime Minister will achieve her objective.

Back in February last year, just after the Prime Minister’s Lancaster House speech, almost as many voters (33 per cent) reckoned that Britain would get a good deal as anticipated that it would emerge with a bad one (37 per cent). But now, in the latest wave of the study conducted during the summer, only 17 per cent say that Britain will get a good deal, while as many as 57 per cent believe it will get a bad one.

Unsurprisingly, many of those who voted Remain in the EU referendum were sceptical from the beginning about what would be achieved. Over half of them (56 per cent) said in February last year that Britain would get a bad deal, while only 17 per cent felt the deal would be a good one. Doubtless their view of what would constitute a ‘good deal’ was very different from what the Prime Minister had in mind anyway. However, at that point at least, a half of Leave supporters believed a good deal would be secured, while just one in five feared the outcome would be bad.
