Jonny Maconie is a fictional character from the BBC medical drama Holby City, played by actor Michael Thomson.

He was introduced along with two other regular cast members by the show's then executive producer Johnathan Young, who wanted more "truthful and complicated" characters in the series.

He also praised the writers for way his character was written, while Katy Moon from Inside Soap was convinced that Jonny would become popular with viewers.

Jonny's storylines have often developed through his close friendship with Mo Effanga (Chizzy Akudolu) and his on-off relationship with Jac Naylor (Rosie Marcel).

Charismatic, cocky and roughish, Jonny has no qualms about telling a few white lies to stir up some mischief, but he'll never compromise patient care and has a long-standing professional relationship with best mate, Mo.On 29 March 2012, it was announced that three new regular characters would make their debuts during Holby City's fourteenth series in May 2012.

[3] Of the new characters, the show's then executive producer, Johnathan Young, commented "These are three very talented actors and I am delighted to welcome them to the cast.

[5] He later told Lorraine Kelly that he loved playing Jonny because even though he was a good guy, he was also flawed and could be "an idiot" at times.

Shortly after their arrival, Mo and Jonny perform a "domino operation", which involves transferring a donor's heart and lungs to two different recipients.

[11] When Jonny began a relationship with Jac Naylor (Rosie Marcel), he started lying to Mo and she felt pushed out.

[12] Mo was upset when Jonny continued to lie about missing their annual barbecue because he was visiting a relative – when he was actually with Jac.

[12] The pair were reunited when they saved the life of a patient who was a Jehovah's Witness, and refused to have a transfusion because the Bible forbids the use of blood.

[11] Elliot Hope (Paul Bradley) threatened to remove Jonny and Mo from the transplant team, after realising there was trouble between them.

[5] The actor later stated that he wanted to make Jac and Jonny's relationship interesting to watch and was pleased that the couple had become popular with viewers.

[15] Speaking to a What's on TV reporter, Thomson said "Up til now, Jac's had him jumping through hoops, but by her saying those words and making that commitment, it blows Jonny's mind and takes their relationship in a new direction.

"[15] While treating a patient, Jac suffered a sharp pain in her side and Jonny assumed that it was something to do with her kidney, which she had removed.

[15] Thomson thought it was not unusual for Jac to hide something from Jonny, because she had built up many defences over the years when she felt scared.

Thomson believed that Jac was afraid to tell Jonny as she knew he wanted a big family, and he might have second thoughts about their relationship.

[16] Jac also considered having an abortion after learning the baby had a congenital diaphragmatic hernia, leaving it with just a 50% chance of survival.

He also said Jonny was dealing with a lot of uncertainty, as the baby's condition led to "an unpredictable set of circumstances" at the happiest time of his life.

[18] Jonny eventually proposed to Bonnie and Peer thought it seemed like the wedding came around quickly, but said that the couple had known each other for a long time.

[19] When Jonny finally made it to the registry office, he asked Bonnie for some money to pay the taxi driver.

[18] Of the scene, Thomson quipped "Finally, Jonny had someone who could make him happy but then, in true Holby fashion, it's ripped away from him.
