Britain in 'technology arms race' against terrorists, MI6 chief warns

Britain is engaged in a "technology arms race" with terrorists, cyber criminals and others who are determined to cause the country harm, the head of MI6 has warned.

Alex Younger said agencies were battling opponents "unconstrained by consideration of ethics and law", who were exploiting internet technology to "put our people and agents at risk".

He said while technology had offered agencies new opportunities to better protect the country, it had also created new vulnerabilities which criminals could exploit.

Mr Younger was making his first public comments since taking over last year as Chief of the Secret Intelligence Service (SIS) - more commonly known as MI6.
