Queen Christens Biggest Navy Ship

Her Majesty is to name HMS Queen Elizabeth at Rosyth dockyard, surrounded by dignitaries and workers.

Her Majesty will officially name the aircraft carrier HMS Queen Elizabeth, which has been under assembly at the yard for nearly three years.

In a break from tradition, she'll smash a bottle of Isla Malt on the bow of HMS Queen Elizabeth.

The whisky comes from the Bowmore distillery - it was the first the Queen visited in an official capacity.

Rosyth is one of six yards around the UK involved in building the Queen Elizabeth and HMS Prince of Wales - another QE class carrier.

Although HMS Queen Elizabeth is being named today, she'll only go into the water int he coming weeks.

And assembly work on the Prince of Wales will begin here at Rosyth, later this year.

First Minister Alex Salmond will be joined by his 92-year-old naval veteran father, Robert, at the ceremony.
