Glasgow's shops are expected to be the busiest in Scotland on this year's Black Friday after a survey found half the city's residents planned to take advantage of sales.

Researchers found bargain hunters in the city intend to spend an average of almost £200 on discounted items - up from £60 last year.

Black Friday is always the day after US Thanksgiving Day and it falls on November 25 this year, with Cyber Monday following on November 28.

A total of 43% of Scots intend to buy goods on one of the two days, while in Glasgow the figure is 51% and in Edinburgh it is 33%.

Edinburgh was also found to be the city in the UK were residents are most likely to avoid the sales, with 23% of people quizzed saying they had "no interest at all" in them.

Consumers were asked how much they intend to spend on average, with the average in Scotland coming in at £187.55. Glaswegians expected to spend £197.79 while for shoppers in Edinburgh the figure was £185.96.

The survey found that across the UK, 42% of consumers intend to buy during the sales, with an average of £202 being spent.

Shoppers in Brighton expect to splash out the most at £300, while people in Bristol intend to spend the least at £121.

Researchers Opinium polled 2000 people for the survey on behalf of PricewaterhouseCoppers (PwC).

Madeleine Thomson, PWC's retail and consumer lead, said: "Even though retailers have mixed feelings about it, our research shows Black Friday and Cyber Monday are definitely here to stay, with sales over the weekend due to grow by a predicted 38% to £2.9bn, and 57% of UK consumers who are planning to shop holding off on planned purchases in anticipation of getting a better deal during the sales period.

"The report also found consumers are embracing online shopping, with 77% of respondents now planning on making their purchases in the sales online, compared to just 17% in store."

Police officers were called to Tesco stores at the Silverburn Centre in Glasgow and the Kingsway in Dundee and on Black Friday in 2014 as shoppers fought over discounted goods.

Last year's event passed without any significant incidents, however, while some retailers took the decision not to participate in the event.

A movement to ignore the event altogether has also grown in strength. Buy Nothing Day has been held on the same day as Black Friday since 1992, with participants choosing to engage in non-commercial activities such as hiking or visiting relatives instead of seeking out bargains.
