The trial of two men accused of plotting to murder Celtic manager Neil Lennon and other high-profile supporters of the club has been adjourned.

Trevor Muirhead, 43, and Neil McKenzie, 42, are accused of sending improvised explosive devices to kill Lennon, former MSP Trish Godman and lawyer Paul McBride QC, as well as various people in the premises of Irish republican group Cairde Na hEireann in Glasgow last year.

The pair have denied the charges and their trial was scheduled to begin at the High Court in Glasgow on Thursday.

However, as Donald Findlay QC, who is defending McKenzie, is involved in an ongoing High Court case in Edinburgh, the trial of the pair has been postponed until Monday.

Muirhead and McKenzie are accused of sending Lennon a package they believed was capable of igniting and exploding, causing severe injury and death.

It is alleged that the package, sent to Lennon at Celtic FC's training centre in Lennoxtown, contained a plastic bottle containing the substance triacetone triperoxide, with a wire attached, and a plastic bag containing a bag of nails and a watch component.

McKenzie, from Saltcoats in Ayrshire, and Muirhead, from Kilwinning in Ayrshire, are also charged with sending similar devices to Ms Godman at an address in Bridge of Weir, Renfrewshire and to Cairde Na hEireann at its Glasgow premises.

It is alleged the package sent to Mr McBride at Advocates' Library in Parliament House, Edinburgh comprised a plastic bottle containing petrol, with wire attached, a plastic glove, nails and a watch component. They are accused of sending the devices with the intention that the contents would ignite and explode when opened, causing severe injury and death to the recipients.

The pair also face the alternative charge that they conspired to cause an explosion likely to endanger life or cause serious injury to property. They face four further charges, including attempting to defeat the ends of justice and sending an item by post to Lennon at Celtic Park on March 3 or 4 last year, intending him to think it was likely to explode or ignite.
