A SELF-STYLED Scottish ­separatist is to be extradited to Scotland over claims he threatened to poison Gordon Brown and contaminate the water supplies of English cities.

Adam Busby, 64, has been told by a judge in Dublin that he will have to return to his homeland to face the terror charges.

The founder of the Scottish National Liberation Army had fought the extradition attempts since being arrested over seven offences in 2010.

It is claimed Mr Busby made hoax calls to media groups in ­Edinburgh and Glasgow and to the Samaritans.

He allegedly threatened "to contaminate the drinking water supplies of major English towns and cities with a noxious substance".

It is further alleged he told a newspaper that packages containing caustic, poisonous or other noxious substances had been sent to various political leaders including Mr Brown, who was Prime Minister at the time.

The warrant further alleges Mr Busby contacted news groups in 2010 to claim that bombs had been placed at various bridges, including the Forth Road Bridge and Erskine Bridge.

Mr Busby is also accused of ­phoning the Glasgow branch of the Samaritans and claiming a bomb was placed at the city's Hilton Hotel.

Mr Busby argued that, as he had been resident in Ireland for 30 years, he should be tried there and removal to Scotland would ­interfere with his family life.

He also stated that he would face a much higher penalty in the UK than if he were prosecuted in Ireland, and argued that the ­application amounted to an abuse of process as the authorities had previously sought to prosecute him on similar offences.

Busby's lawyer also stated that he would face a much higher penalty in the UK than if he were prosecuted in Ireland, something with which he said he had no difficulty.

At the High Court in Dublin Mr Justice Edwards said the fact he was going to be exposed to a higher penalty in Scotland would not constitute an abuse of process.

He said it was legitimate to argue that because the results of his alleged actions were felt in Scotland, the Scots could legitimately claim jurisdiction.

He said that counsel for the Justice Minister had argued that these were result-type offences and that the result had been felt in Scotland.

He said that it was legitimate to argue that because the results were felt in Scotland, the Scots could legitimately claim jurisdiction.

He said that one offence was characterised as threats and had a maximum sentence of life in prison.

He said another offence had been labelled hoaxes involving noxious substances and that the remaining four offences included bomb hoaxes.

He noted that each of the hoaxes carried a penalty of up to seven years imprisonment.

Ordering the surrender of Mr Busby under the European Arrest Warrant, he said: "What was done, if done as alleged, was intended to terrorise."

Mr Justice Edwards made order for the surrender of Busby under the European Arrest Warrant Act and remanded him in custody to Cloverhill Prison in Dublin.

Busby, originally from Paisley, Renfrewshire, moved to Ireland in 1980.
