FTSE 100 sinks into red as markets doubt Trump's ability to deliver tax cuts
London's premier index followed global stocks into the red as investors took a dim view of the US president's ability to deliver tax cuts and fresh infrastructure spending.
The FTSE 100 Index closed lower by nearly 0.6% or 43.32 points at 7,293.5 as European markets doubted whether Donald Trump could honour his campaign promises after failing to push through a repeal of Obamacare.
Across Europe, Germany's Dax fell nearly 0.6% while the French Cac 40 dropped by around 0.1%.
The fallout was also hitting the currency markets, with the pound enjoying an uplift after the US dollar sank in response to President Trump's withdrawal of the healthcare bill on Friday.
Sterling was up 0.9% against the greenback at 1.258 and rose 0.1% versus the euro to 1.156.
Jasper Lawler, senior market analyst at London Capital Group, said: "Stocks were under pressure on Monday following the collapse of Donald Trump's first attempt to overturn Obamacare.
"For many, the healthcare bill has been the moment that crystallised the risk of economic failure under The Donald.
"Ironically, the reaction in currency markets to his healthcare failure will suit Donald Trump. Trump wants to improve the competitiveness of US companies abroad and a weaker dollar will help him deliver it."
