Sam Smith has made UK chart history with his new James Bond theme.

The 23-year-old singer is ''so proud'' that 'Writing's On The Wall' from the upcoming film 'Spectre' has become the first Bond track ever to reach number one after it achieved combined chart sales and streams of 70,000 copies.

He told OfficialCharts.com: ''It was such an honour to be asked to write and record 'Writing's On The Wall' and it's incredible that it's become the first Number 1 Bond theme song. It's been an unforgettable experience working with Barbara [Broccoli] and Sam [Mendes] to become part of this British legacy. I couldn't have done this without my fans - this is a special moment I'll never forget.''

The previous highest-charting Bond themes were Adele's 'Skyfall' in 2012 and Duran Duran's 'View To A Kill' in 1985, which both peaked at number two.

Speaking to BBC Radio 1 after the news was announced, the British star added: ''Out of all the songs I've brought out in my life, I was not expecting this to even chart in the top 10, let alone number one. It's unbelievable.''

The full music video for the track will be unveiled by Sam, who sold 13,000 more units than his closest competitor, Justin Bieber's 'What Do You Mean?,' at 00.07am on Monday (05.10.15) in honour of Global James Bond Day.
