London — The UK has retained its place in the top ten countries worldwide for ease of doing business, despite Brexit uncertainty and warnings from British business leaders.

This year's Ease of Doing Business report by the World Bank puts the UK above many of the world's leading economies, including Germany and France, and the ease of starting a business has actually improved.

The ranking uses 11 indicators to measure aspects of business regulation across 190 countries worldwide. Of the top 20 economies in the list, 14 are high-income OECD economies.

However, many countries are implementing significant reforms: India is one of the top ten to have improved most this year, although it still ranks 100th. Sub-Saharan Africa now has the widest variation in performance across the countries ranked: while Mauritius comes in 25th place, Somalia is 190th.

Keep scrolling for the top 12 economies in the ease of doing business ranking:

12. Estonia — same place as last year.

This country performs particularly well for registering property, which takes an average of 17.5 days and costs 0.5% of the property's value, and for starting a business, which takes an average of 3.5 days.

11. Macedonia — down from 10th last year.

This is the only upper-middle-income economy on the list, and has carried out the second highest number of reforms among the top 20. These have included sweeping construction reforms, which significantly reduced the number of procedures and time it takes to build a warehouse.

It also scores particularly highly for protecting minority investors, coming in 4th overall.

10. Sweden — down from 9th last year.

Sweden has especially good information available about properties, including an online system allowing anyone to freely access ownership information and maps dating back 400 years.

Meanwhile, it takes an average of seven days to start a business, and two years to resolve insolvency.

9. Georgia — up from 16th last year.

This is the only lower-middle-income economy in the top 20, and has implemented the highest number of business regulation reforms (47) since the World Bank began the ranking in 2003.

This year, Georgia improved on the ease of resolving insolvency, ease of accessing electricity and strength of shareholder rights, including how easy it is for minority investors to sue directors.

8. Norway — down from 6th last year.

This year Norway made paying taxes less costly by reducing the statutory corporate income tax rate.
