The head of the secret intelligence service - better known as MI6 - says there is no one 'type' of person who should consider becoming a spy.
At a rare public appearance in St Andrews, Alex Younger urged young people from every background to consider a career in intelligence, particularly those skilled in technology.
He also spoke about how his agents have prevented 'multiple' attacks by so-called Islamic State, and about the dangers being posed by Russia.
And he echoed the words of the British foreign secretary by saying that he is 'perplexed' by the case of British student Matthew Hedges.
He was pardoned by the UAE Government last week, after being sentenced to life imprisonment in the Gulf state on spying charges, which he denies.
Mr Younger is a former student of th eUniversity of St Andrews, where he spoke on Monday morning.
He graduated with a degree in economics before joining the Army.
