Battle of Britain museum opens in London
A £9.5m museum to commemorate the Battle of Britain in the RAF's headquarters of the time is set to open in north London.
Bentley Priory, in Harrow, was the headquarters of Fighter Command in the summer of 1940.
The rooms of Bentley Priory's mansion house will now be open to the public for the first time in 80 years.
Project manager for the Bentley Priory Battle of Britain Trust, Erica Ferguson, gave BBC News a first glimpse inside.
