The Union Flag painted on a Royal Air Force Voyager "is on properly" Downing Street says, after questions were raised online.
The paint job, part of a £900,000 maintenance project on the UK military aircraft used by VIPs, was revealed to the public for the first time yesterday.
The plane is known as 'Vespina' and flew from Cambridge to RAF Brize Norton yesterday afternoon.
The Voyager, which is used to transport the Prime Minister, royals and senior cabinet ministers, has gone from grey to bright white, with a Union Flag on the aircraft's tail and a blue stripe, funded by the Ministry of Defence.
Downing Street has insisted the Union Flag has been correctly painted on to the aircraft, after questions were raised online.
"When a flag is on an RAF aircraft it’s represented as been flown on a flag pole," a Number 10 spokesperson said.
"So as a result when you look at it from the left side it will be correct in the normal sense, when you look from the right it will be inverted.
"So it is on properly."
