LONDON, June 22 (Reuters) - German-owned discount supermarket Lidl can have an injunction to stop rival Tesco (TSCO.L) copying its logo, London's High Court has ruled, despite hearing it will cost Tesco nearly 8 million pounds ($10.2 million) to remove them all.

Britain's biggest retailer Tesco in April lost a trademark lawsuit brought by Lidl after Tesco adopted a yellow circle against a blue background to promote its "Clubcard Prices" discount scheme.
