Manuals with bomb-making instructions, using items such as weedkiller, lighter fluid and sugar, were found at his flat, a Grimsby Crown Court jury heard.

Nathan Worrell, 35, of Grimsby, denies charges of hoarding bomb-making materials and waging a racist campaign.

The court heard racist stickers were left on the gate and a lamp post near the couple's home.

Ku Klux Klan

David Farrell QC, prosecuting, told the jury of other discoveries at Mr Worrell's flat.

Also found were numerous boxes of matches, 171 match heads, two tubs of sodium chlorate weedkiller and three bottles of lighter fluid, he said.

These items featured in the manuals and books found in the flat.

Fireworks, some of which had been tampered with, were also found in the flat, the jury was told.

Mr Farrell alleged they had been tampered with in order to get at the gunpowder inside.

The jury was also shown a video by the extreme far right group Combat 18 showing how to prepare and make a bomb from household items, which was found in Mr Worrell's flat.

White nationalist

A significant amount of racist and far-right propaganda was also found, as well as membership cards of groups such as the Ku Klux Klan, the November Ninth Society, and the British People's Party.

Mr Worrell admitted to police in interview that he was a white nationalist, Mr Farrell told the court.

He also said unemployed Mr Worrell signed his texts off as "88" - the sign for Adolf Hitler.

Mr Farrell said the stickers were "plainly aimed" at causing the family, who had a new-born baby, "harassment, alarm or distress".

He told the jury that piles of the stickers were found by police at the defendant's home.

The case continues.
