Mothercare said its overseas sales have overtaken British figures for the first time. The company extended plans for new overseas store openings this year from 100 to 150, which would increase selling space by a fifth. That would push the total number of stores up to 1,270 in 54 countries. But while the international business is booming, the UK remains tough. Same-store sales fell by 3.2 per cent during the second quarter to end-September while international sales rose 14 per cent.
