UK 'flash crash' trader to fight extradition to US

A financial trader has told a court in London he will fight extradition proceedings to the United States where he is accused of manipulating share prices.

It is claimed 36-year-old Navinder Singh Sarao caused a sudden crash on Wall Street in 2010, and US prosecutors say he made $40m (£27m) over five years.
