Jeremy Clarkson swapped Porsches for potatoes as he threw open the doors to his farm shop for the first time.

But his venture stalled as customers were forced to go back home because of the wet and muddy conditions.

The former Top Gear presenter, 59, launched 'Squat Shop' – which promises produce cheaper than Aldi – at his farm Diddly Squat near Chipping Norton in Oxfordshire on Saturday.

The Grand Tour presenter, known for his no-nonsense attitude, sold eggs, horseradish and potatoes, which – at £1.02 per 2kg – were 'less than Aldi', a sign said

About 100 people turned up, transforming the makeshift car park into a quagmire as vehicles battled with the mud.

Some customers said they had not been allowed in.

One visitor who had to turn around tweeted: 'We're gutted, pulled up outside but too muddy for a pushchair.'

Clarkson replied: 'I know. Bloody nightmare. Sorry.'

The goods were labelled 'non-organic' and one sign even boasted of them being 'drizzled in fungicide'.

Shelves with 'mildly organic' horseradish and 'good exercise chicken eggs' were soon empty.

Elsewhere, Clarkson put out a jokey health and safety sign telling visitors 'do NOT catch fire' near an open fire.
