The sale of one of Norfolk's largest agricultural supplies businesses looks set to go ahead after it was cleared by the Office of Fair Trading.

As reported earlier in the year, the owners of Great Yarmouth-based fertiliser producer J&H Bunn have agreed in principle to sell the business to subsidiary of Koch Inudstries, the world's largest private company.

Koch has pledged to retain all of Bunn's 150-strong national workforce and it is thought the 50 staff at Yarmouth could eventually grow to at least 75.

Bunn, founded in 1816, has an 18pc share in the UK fertiliser market, but it is understood Koch has ambitious expansion plans.

The value of the proposed sale is expected to be an eight-figure sum.

In addition to the main J and H Bunn operation, the acquisition will see Koch take over seven regional subsidiaries and brands in East Anglia, Humberside, Teesside and Scotland. They include Yarmouth haulage contractors Spandler Brothers.
