First appeared: 1965

After his mother's death, Peter lived in Glasgow with his maternal grandparents, but came down to Weatherfield to see his father from time to time - curiously his appearance altered each time !

Peter served in the navy for many years. He married Jessica but after she was unfaithful, he left the navy and came to Weatherfield with a chip on his shoulder. He got involved with several local woman including Karen Philips (later McDonald) and had flirtations with Linda Baldwin as well. He got into a car accident and gave his father's name instead of his own but convinced Ken to cover for him. He worked in the Rovers for awhile under Duggie's management and was discovered sneaking booze and not paying for it. Toyah Battersby found out and Peter was angry at her for causing him to lose his job. He was suspected of raping Toyah not long after but was cleared and was then instrumental in helping to capture Toyah's actual rapist, an acquaintance of hers.

Peter got work at the local bookies and when the opportunity came up to buy the place, Peter stole some money from the dodgey owner, making it look like a break in and using Karen as cover which caused some ructions between her and her now husband, Steve. He ran the bookies fairly successfully however, renting the flat over top to young couple Sarah Platt and Todd Grimshaw. He started dating Shelly Unwin who was working in the Rovers and they moved in together in a flat next to the one over the bookies. His old navy pal Ciaran McCarthy came to visit. Ciaran seemed jealous of Peter's success and happiness and came on to Shelly one night. Shelly firmly rejected him but he told Peter that Shelly was the one that came on to him. Peter believed Ciaran and Shelly moved out.

They got back together though, and Ciaran was chucked out on his ear. At their engagement party, however, Ciaran returned. Shelly was angry when she found out that Peter was still friends with Ciaran but backed off eventually. Ciaran moved into Peter's flat when Peter moved in to the Rovers with Shelly.

Peter met florist Lucy Carmichael when he was buying a bouquet for Shelley. He was immediately intrigued and soon began an affair. They broke off for awhile but when Tracy was hired by Lucy who had no idea of the connection between Tracy and Peter, and Tracy told Peter that her employer was pregnant, he realized the baby was his. He talked his way back into her heart and married her although he was living with and engaged to Shelley at the same time. As you might expect, it all ended in tears and Peter probably has broken the Corrie record for shortest marriage on the books. Lucy chucked him out days after the wedding when she realized Shelley was still in his life.

Peter's son Simon was born in early July 2003 but at first Lucy didn't want Peter to be involved at all. She relented a little and allowed Peter to see Simon for brief periods. Peter was torn over wanting to be with his son and marrying Shelly. His soon to be mother in law, Bev, was suspicious of him and told Shelly. Peter admitted on the day before the wedding that he had had an affair but it was long over and he really wanted to marry Shelly. (But the divorce from Lucy wasn't complete yet!) Shelly agreed to marry Peter after all.

Shelley and Peter got married in a big, beautiful church wedding in July. Shelley found out that Peter had had an affair but since he insisted it was long over, she married him anyway, deciding to trust him. Of course it wasn't too long before Lucy and Shelley found out about each other and Shelley found out about Peter's baby with Lucy and by the end of the summer, Shelley had kicked Peter to the curb for good. Lucy and Shelley were determined to make Peter pay and they had a good hand in nearly ruining his business and reputation. On charges for bigamy, Peter left town for awhile but returned. He was let off with a fine and a warning. Lucy's final revenge was allowing Peter to think she wanted him back and wanted them all to move to Spain. Peter discovered that she was actually leaving and moving to Australia without him. He could do nothing to stop her and resigned himself to never knowing his son. He left Wetherfield shortly after.
