Business Insider article The UK’s Christmas shopping season is set to kick off in earnest this week with a number of big-ticket retailers announcing that they will be bringing their big-selling items to stores, as well as launching a wide range of discounts and savings opportunities.

The big four retailers, Tesco, Lidl, Sainsbury’s and Marks & Spencer, have all said that they expect to boost sales in the first half of the year by up to 25% on the previous year.

The UK has seen an uptick in holiday sales as people have been stocking up on Christmas gifts for the festive season, but the industry has also been hit by a string of bad weather, with sales in some areas being down.

Tesco said that it expects to see a 25% jump in sales in Christmas 2018 compared to the previous 12 months, which would be its largest year-on-year increase in two decades.

The company also said that its average sales in January were up by 7% over the previous 24 months, while the company said that average sales over the holiday period were up 3.6% in the month of January. 

Lidl also said it expects its holiday sales to increase by 20% in 2018 compared with the previous holiday period. 

Sainsbury has also said its average Christmas sales will be up by about 15% over 2018. 

Marks & Spencer has also increased its average holiday sales by 15% in 2017. 

The UK is expected to be the best performing economy in the world for the Christmas period, according to a new report by the UK’s National Institute for Economic and Social Research (NIESR).

The research, which was released on Tuesday, showed that the UK was the only country to be able to keep its growth rate on track.

The report also said the UK will overtake Germany in terms of GDP per capita growth by the end of 2019, which is a boost to the economy and a boost for the government’s tax-raising plans. 

“The UK’s growth trajectory is robust, with a strong recovery of the economy, and a clear return to a more sustained growth rate,” NIESR director Mark Carney said in a statement.

“The government’s measures are well positioned to deliver on its ambitious economic recovery agenda.” 

However, the economy is facing challenges as the economy continues to struggle with the fallout from the Brexit vote. 

Last month, a poll showed that only one in five Britons believed the government was doing enough to tackle the Brexit uncertainty.

The NIESr found that the government has been unable to make the most of the “big picture” in its plan to tackle uncertainty.

It also found that just 13% of the population is satisfied with the way the government is dealing with Brexit.
