Consumer confidence among Brexit supporters has fallen, according to a survey taken immediately after the triggering of Article 50.

The latest Nielsen Survey of Consumer Confidence and Spending Intentions revealed that confidence among leave voters fell from 109 in January to 106 in early April, while the level among remain voters increased one point to 97.

British consumer confidence overall remained stable at 102.

A score over 100 indicates degrees of optimism, with a score under 100 indicating pessimism.

The online survey of 500 UK consumers between March 30 and April 3 also revealed that 'strong support' for Brexit among leave voters has steadily declined, from 74% in December to 68% in January, and down to 63% after Article 50 was triggered.

Furthermore, 3% of leave voters now oppose Brexit, but 10% of those who originally supported Remain have now shifted their support to Leave.

Steve Smith, managing director of Nielsen UK and Ireland, said: 'Although immigration concerns have dropped, leavers are starting to worry more about everyday matters, particularly rising utility bills and food prices.'

He added: 'Inflation is creeping in and as it could be as high as 3% by July. Consumers believe this will translate to price rises across the board.

'However, overall consumer confidence remains stable and we know that brands and retailers are working closely together on solutions to minimise any price impact on shoppers.'
