Burberry jumped 3.5% as underlying sales fell 9% in the three months ended December, but the company said it remained confident in the future, buoyed by sales growth of 11% in Asia-Pacific stores.

The blue-chip FTSE 100 index was up 0.1% by 0807 GMT after Asian shares hit a record high following US Treasury Secretary nominee Janet Yellen's call for more fiscal support.

Prime Minister Boris Johnson said he looked forward to working closely with Joe Biden after his inauguration on Wednesday as US president, highlighting the shared interests of the two close allies.
