FTSE dragged lower by mining stocks
London's main benchmark was buoyed by more conciliatory foreign policy tone set by US President Donald Trump Reuters

Blue chip shares started the week in positive territory, buoyed by more conciliatory foreign policy tone set by US President Donald Trump.

In recent days Trump has held meetings or taken phone calls from the leaders of Japan, China and Canada and appeared to row back on the more hardline elements of his campaign pledges.

In a call with Chinese President Xi Jinping, Trump reportedly accepted the long-standing American One China policy that does not officially recognise Taiwan, which China believes to be a breakaway province. The US president also played down his opposition to existing free-trade agreements it has with Japan and Canada.

The FTSE 100 Index closed up 20.2 points to 7279, as the European Commission became the latest institution to upgrade its economic forecasts for the UK economy projecting 1.5% growth, an upgrade from 1% it made in November.

The FTSE 250 Index hit a record intraday high of 18,775 at noon, and closed up 43.4 points at 18,759 points.

CMC Markets chief market analyst Michael Hewson said traders were reassured by "the more positive risk environment, helped in no small part by a more pragmatic tone from President Trump to China and Japan relations".

In London, the Royal Bank of Scotland will ditch 15,000 jobs and is expected to post its ninth year of consecutive losses next week, according to media reports. However, shares lifted 5.7p to 234.6p, with investors cheered that the bank appears willing to slash costs.
