The travel brand, which is part of Tui UK and Ireland, will show the event at 8.30pm tonight (February 29) during Coronation Street on ITV.

The 60-second spot will be fronted by TV presenter Laura Whitmore.

After a nationwide hunt and a series of auditions, in addition to the live couple, First Choice will also help two other women bring their dream leap year proposals to life.

Shorter formats – 15 and 30 seconds – of their proposals and back stories, as well as montage film of the three couples, will be shared online and hosted on a landing page of the First Choice website.

Jeremy Ellis, marketing director, Thomson and First Choice, said: “This is a really exciting activation for us, and it’s totally different to anything we’ve done before.

"For us, in today’s environment, it’s about so much more than focusing on sales, it’s about producing engaging content, telling great stories and trying to reach new and core audiences in a different way.

"We just felt that this fits so well with the First Choice brand philosophy of ‘Life’s too short to say no’. Finally we’d like to say a huge thank you to the couples involved. We hope to get a yes from all three and then we’ll be back in touch to help them plan their honeymoons.”
