Lego’s boss has said the failure Toys R Us has not knocked his turnaround plans off-course, insisting “we have come out as strong”, but the company is not aiming to return to its former stellar level of growth.

Niels Christiansen, who replaced British-born Bali Padda as chief executive a year ago, said Lego would not be tempted to chase the “supernatural growth” it had experienced until the last few years.

Mr Christiansen told The Daily Telegraph that after “a couple of difficult years in 2016 and 2017”, changes he has implemented had started to bear fruit.

While half-year profit before tax fell 10pc to 4bn Danish krone (£483.5m) on revenue that was 5pc lower at 14.3bn krone, the results were skewed by a strengthening of the US dollar. Sales rose 1pc and operating profit was 4pc higher on a constant currency basis.
