Consumer confidence in Northern Ireland has fallen amid Brexit uncertainty, a survey has found.

Around a quarter of those canvassed felt the planned withdrawal from the European Union weighed on the level of optimism, Danske Bank said.

The bank's Northern Ireland Consumer Confidence Index fell to 136 in the second quarter of this year, down from 139 in the first quarter of the year but above that registered in the second quarter of last year.

Danske Bank chief economist Conor Lambe said: "With a new Prime Minister now in place, the Brexit process is likely to dominate UK politics in the weeks and months ahead.

"This survey continues to show that, like the business community, consumers also have concerns around how the UK will leave the EU.

"The outlook for consumer confidence, and indeed overall economic growth in Northern Ireland over the rest of this year and into next year, will be heavily dependent on how the Brexit process unfolds over the coming months and whether a no-deal Brexit can be avoided."

After rising on the back of the strong labour market at the start of this year, consumer confidence fell back in the second quarter of 2019.

Mr Lambe added: "The main areas of concern for local people continue to be the lack of an Executive at Stormont and Brexit.

"39% of people said that the fact we haven't had a functioning devolved government in two-and-a-half years was the issue that had the largest negative impact on how they were feeling.

"With regards to leaving the EU, 14% of people stated that progress during the Brexit negotiations in recent months negatively impacted them and a further 10% highlighted the UK Government's longer-term Brexit objectives as the main factor that weighed on their confidence levels."

He said confidence in the second quarter of this year was higher than in the same period of 2018.

"This was likely due to the fact that the labour market was still providing some upward support to consumer sentiment.

"The latest labour market figures which covered the period March-May 2019 showed that, when compared with the same period last year, the employment rate was higher, the unemployment rate was lower, and the economic inactivity rate was also lower.

"A quarter of the respondents to our survey said that rising wages was the factor that had the largest positive impact on their outlook in the second quarter of the year." 

Meanwhile, a group representing retailers in Northern Ireland has welcomed plans for £300 million in additional funding for growth deals for regions with devolved powers in the UK.

Glyn Roberts, chief executive of Retail NI, said it wasn't clear as yet how much of the disbursement Northern Ireland would receive.

He said it was a welcome development, but there was a caveat.

"The full potential of these deals can only be realised if we have devolved ministers. This funding plan is a three-legged stool; there's money from Westminster, money from the private sector and money from the executive.

"If there's no executive, how can we secure that third? There are challenges as to how we can proceed without a government," he said.

Glyn Roberts also appealed to businesses in the North to step up their preparations for Brexit as no-deal becomes a serious prospect.

"There's concern that since the new Prime Minister has been appointed there has been a fallback or a default narrative that a no-deal is now a serious option. It can't be. 

"Our economy department said a no-deal would cost Northern Ireland upwards of 40,000 jobs. That's 7% of all private sector employment. It's simply a lot of jobs that the economy can't afford to lose."

The British Prime Minister, Boris Johnson, is expected to visit Northern Ireland later this week.
