German discounter Aldi has announced plans to open an additional 80 stores in the UK this year as it continues to expand its presence in the British market. The news is the latest part of a £600m investment plan for its UK business announced by Aldi in 2014.With these new stores, the number of Aldi branches in the UK will rise to around 700, at a time when the larger multiples in the UK are cutting expenditure by closing stores, trimming staff numbers or shelving expansion plans.
