The Duke of Cambridge has spent a "humbling" three weeks on work placements with three of Britain's security and intelligence agencies.

Axar.az reports citing BBC.

MI5, MI6 and GCHQ were "full of people from everyday backgrounds doing the most extraordinary work to keep us safe", Prince William said.

GCHQ's head of counter-terrorism said the duke worked "exceptionally hard".

The royal learned about risks to the UK's national security and economy, Kensington Palace said.

He also observed counter-terrorism teams analysing intelligence and carrying out investigations.
