A lawsuit alleging that Donald Trump and a real estate development firm misled investors, has been upheld by Canada's highest court.

Sarbjit Singh and Se Na Lee alleged they were sold units in Toronto's, Trump International Hotel, under false pretenses. The pair claimed they were misled to believe their investments would see returns ranging from 7.7 per cent to 20.9 per cent. Instead, they said they lost a combined C$1.2m (£732,810).

The Ontario Court of Appeal last year, sided with them in their case against Mr Trump, Talon International Development and former executives of that firm. That decision was backed by The Supreme Court of Canada which upheld the lower court's ruling and refused to hear an appeal from the defendants.

In a document outlining the case, Justice Paul Rouleau wrote that “neither Mr Singh nor Mrs Lee were sophisticated investors, in real estate or otherwise" and "both had to borrow heavily from family to finance their purchases."
