Diageo has been launched in the heart of Scotland's capital city. Four and a half years in the making, Johnnie Walker Princes Street is the centrepiece of Diageo's £185million pound investment in Scotch whisky tourism in Scotland – the largest single investment programme of its kind ever seen in Scotch whisky tourism. To mark the opening a Johnnie Walker flag was raised above the landmark building by Ivan Menezes, Chief Executive, Diageo, and Barbara Smith, Managing Director of Johnnie Walker Princes Street, against the backdrop of Edinburgh's iconic skyline, including the world-famous Edinburgh Castle.
