Home and Away will air a surprise proposal in the soap's 2011 finale week, it has been revealed.

TV Week reports that one Summer Bay resident will soon get down on one knee and pop the question in the latest romance twist for the show.

Firm details of the characters involved are being kept under wraps. However, with the news that someone will be receiving an engagement ring, the magazine has named Bianca Scott and Leah Patterson-Baker as the two most likely ladies.

The news means that one possible outcome is Bianca and Liam Murphy's (Axle Whitehead) relationship progressing to the next level in the aftermath of a recent road accident that brought them closer together again.

Lisa Gormley, who plays Bianca, told the publication: "Almost losing him put everything into perspective. The reason why they broke up before wasn't because she didn't love him, but because of circumstances - his addiction, his lying, her rape. This is probably the best relationship she's ever been in."

Meanwhile, if Leah is the one who receives the proposal, either current partner Miles Copeland (Josh Quong Tart) or her ex Elijah Johnson (Jay Laga'aia) could be the man who pops the question.

Ada Nicodemou, who portrays the role of Leah, commented: "She's been really, really unlucky and I feel for her - I'd just love for Leah to be happy."

Home and Away will air these scenes later this month on Network Seven in Australia and early next year on Channel 5 in the UK.
