Home Secretary Priti Patel has approved the extradition of a British tech tycoon to the US to face criminal fraud charges.

The decision comes after Mike Lynch, the founder of Autonomy, lost a multibillion-dollar fraud action in London on Friday.

His firm was sold to US giant Hewlett Packard for $11bn (£8bn) in 2011.

He is accused of manipulating its accounts to inflate the value of the company before its sale.
