Senior employee of bra tycoon Michelle Mone quit firm 'after discovering his office had been bugged' Scott Kidlay, 35, told a Glasgow Employment Tribunal he found the device hidden between artificial flowers He was the Operations Director at MJM International at the time Said he was 'horrified' by the discovery and was told it was installed for 'business strategic' reasons Former employee: Scott Kilday, 35, told the Glasgow Employment Tribunal that he found 'bugging' devices hidden in artificial flowers A senior employee of bra tycoon Michelle Mone walked out after discovering his office had been bugged, an employment tribunal heard. Former director Scott Kilday, 35, said he was 'horrified' after he found a listening device hidden between artificial flowers. It came shortly after he was asked to resign from his post as Operations Director at Miss Mone's, company, MJM International. Mr Kilday was allegedly told the bug had been planted for 'business strategic reasons'. The former employee made the accusations on the first day of his employment tribunal in which he is claiming unfair dismissal against MJM. The hearing in Glasgow was told how matters became 'difficult' within the lingerie company after Miss Mone split with her husband and business partner Michael in December 2011. Mr Kilday said: 'It all became a bit disjointed and basically there came a time Michelle and Michael could not sit in the room together. With both being majority shareholders it was very difficult to get an any decision made, which ultimately was the fall of the business. Mr Mone eventually left MJM days before another company, MAS Holdings, bought into the business in February this year. Mr Kilday said it was around the same time Miss Mone asked him to resign as a director. He told the tribunal: 'She said that MAS had asked for me to resign as director for the sale of the company to go through. Mr Kilday's lawyer John McMillan asked: 'What was your reaction?' He replied: 'Obviously I was not particularly pleased, but I acknowledged it with Michelle and afterwards I sought legal advice on my position.' He considered resigning because he did not feel he could trust Miss Mone and set up a meeting with the chairman Eliaz Poleg. Chief Executive: Michelle Mone OBE, pictured, allegedly asked Mr Kidlay to resign as a director at around the same time another company, MAS, had bought shares in the business But, just days before this meeting, he claimed to have discovered a bug in his office by chance. He said: 'We actually had a tanning product (at the time) and just in front of the plant pot I had samples of this product. They were sitting there not in a particularly tidy state. This day when I looked over there were in a tidy state to which I found very unusual. I went over, had a look in the pot and saw a cable coming out, which was wrapped around the articifial flowers. Mr Kilday told his lawyer he was 'horrified' after the discovery and said the only information he could unearth afterwards was that Miss Mone had been signing in late at night to the offices using her husband's 'swipe in' card. Court: Mr Kidlay told an employment tribunal in Glasgow (pictured) he found the device by chance when items in his office had been tidied without his knowledge Mr Kilday later confronted an official from MAS, Kanishke Manakkara who denied any knowledge of the bug's existence. But, the tribunal heard it had been accepted the bug had been set up for 'business strategic reasons' and that it was Mr Poleg who authorised it. Mr MacMillan asked what Mr Kilday did after the discovery and he said: 'I left.' It emerged that Mr Kilday now works for Mr Mone's company Pendulum Apparel. MJM contest the claim of unfair dismissal and the hearing, which is set to last for three days, continues.
