BBC Store has animated a lost episode of Dad's Army.

The selected episode is A Stripe For Frazer - which was Episode 5 of Series 2 of the classic sitcom. First broadcast on the 29th March 1969, it hasn't been seen since.

The episode is no longer viewable as it was one of those which was wiped from the archives. The BBC explains: "Three episodes from the second series are missing as many tapes of programmes from this era were either recorded over or discarded. But a recently recovered high quality audio recording of one of these, A Stripe For Frazer, means that an animated version of that story of can be created."

The episode sees Captain Mainwaring makes Frazer a Lance Corporal but soon regrets doing so. Newly promoted Frazer vies with Lance Corporal Jones for Mainwaring's favour and resorts to issuing a series of increasingly bizarre charge sheets, much to the consternation of Mainwaring and other members of the Platoon.

The 30 minute animation will be published in February, the same month that the new feature film will be released into cinemas. It'll be exclusively available via BBC Store, the corporation's new digital shop via which audiences can buy their favourite BBC programmes.

Jonathan Green, Director of BBC Store, says: "As the UK renews its love affair with Dad's Army we're delighted to be bringing fans an exclusive chance to buy this brilliant lost episode which has been missing from the Dad's Army portfolio for nearly half a century."

BBC Store is now inviting fans to nominate their favourite episodes for inclusion in an exclusive BBC Store 'Best Of Dad's Army Collection'. You can tweet suggestions to @BBCStore with the hashtag #BestDadsArmy or post on the BBC Store Facebook page.

A Stripe For Frazer will be released on BBC Store on Thursday 4th February 2016.
