BBC One has gone down tonight.

The channel began to lose signal just after 7pm.

As the channel went down, it replaced moving images with smooth jazz music alongside a message which read: "We are sorry for the break in this programme and are trying to correct the fault."

Panorama had been on air at the time.

People were quick to share the news on Twitter.

One user wrote: "Absolute scenes in bbc one headquarters as people scramble to find Bob the IT guy who went for a fag break 45 minutes ago."

Another said: "BBC One’s new drama has got me GRIPPED."

A third joked: "BBC One is broken and this is honestly the best live TV I’ve had in weeks listening to the voice over guy panic whilst updating everyone."

And another said: "This is the most excitement I've had all week."
