Neil Lewington denies a total of eight charges
An alleged white supremacist said to have been preparing a terror campaign targeting ethnic minorities was just an "oddball", the Old Bailey has heard.
Neil Lewington, 43, of Berkshire, denies eight terrorism charges linked to claims he was making a bomb factory in his bedroom at his parent's home.
His defence told the court he was a "fantasist" and there was not enough evidence to prove the case against him.
Mr Lewington was arrested at Lowestoft railway station in October last year.
He was allegedly carrying the components for two home-made bombs at the time.
David Etherington QC said his client was "fantasising to make up for a rather sad life".
A search of Mr Lewington's home turned up a notebook entitled "Waffen SS UK members' handbook" and what prosecutors called a "production line" for bombs.
Mr Lewington, of Tilehurst, Reading, denies eight charges including preparing for terrorism, having articles and documents for terrorism, and possessing explosives to endanger life.
Mr Etherington asked the jury: "Is he the real deal? Is he a terrorist or is he just a big pest, a nuisance?"
He suggested the defendant was a "silly immature alcoholic disfunctional twit, fantasising to make up for a rather sad life".
The evidence about him had more of "the air of tragi-comic sitcom than The Professionals and The Day of Jackal", he added.
The trial continues.
