With consumer spending subdued and a national election creating new uncertainties, retailers have been hoping for a boost from Black Friday discount events that were first brought over from the United States by Amazon in 2010.

The number of payment transactions in Britain as of 1000 GMT on Black Friday was up 12.5% from last year, initial data from Barclaycard showed, bringing some cheer to British retailers who have weathered Brexit concerns and weakness on the high street this year.

Following are the highlights:

OCADO Group Plc

British online supermarket Ocado said on Dec. 12 it expects its best festive season ever.

SUPERDRY Plc

Superdry said on Dec. 12 that it recorded its strongest online Black Friday day ever.

TED BAKER Plc

The British fashion retailer said on Dec. 10 that trading over November and Black Friday was below expectations, with lower than anticipated margins and sell through.

Its troubles deepened on Tuesday with the sudden exit of its CEO and chairman as it issued another profit warning and suspended its dividend.

BRITAIN GROCERY SALES

Sales growth at Britain's supermarkets slowed in the last quarter, industry data showed on Tuesday, as shoppers delayed their Christmas preparations ahead of a national election on Dec. 12.

Britain's big four supermarket groups - market leader Tesco, Sainsbury's, Asda and Morrisons - recorded sales declines over the period.

QUIZ Plc

The retailer said it was "pleased" with sales across the recent Black Friday week, without disclosing the actual numbers.

The management said on Dec. 4 they have seen demand for sequinned and sparkly dresses, making for a record Black Friday week.

BOOHOO GROUP

The online fashion group said on Dec. 3 that trading has remained strong across its key brands with a record performance across the Black Friday weekend.

DIXONS CARPHONE

The retailer's Carphone Warehouse business said on Nov. 29 it had seen three orders per second on its website since its Black Friday sales went live. Apple iPhone 11, Apple iPhone XR, and Samsung Galaxy S10 were the most popular products so far.

The department store group said the busiest shopping hour online between midnight Nov. 28 and midday Nov. 29 was between 0900 GMT and 1000 GMT. The most popular searched-for products were Lego, iPads and Airpods.
