Both women later reported him to the police.
Helen, 53, married Gundry in 1998 and while they split for several years, he had told her he wanted to get back together.
She agreed to give things another go – with no clue he had married Susan.
Helen was stunned when she saw him on TV – when he had claimed he was working in Dubai.
At the time, Helen wrote on the show’s official Facebook page.
‘I loved the wedding and the surprise guests,’ she wrote. ‘I didn’t love the sight of my husband who’s supposed to be working in Dubai arriving on the arm of another woman, a woman he’s supposed to have split from last year.’
This week, Gundry was jailed for six months after admitting bigamy.
In addition, he was ordered to pay a victim surcharge of 115 pounds for causing the women ‘embarrassment, shame and humiliation’.
