A Whitchurch schoolboy is set to star in a national retailer’s Christmas national TV advertising campaign tomorrow after winning a Facebook competition launched by Argos.

Harry Nicholls, whose mother Michelle entered him into the competition, is one of three lucky children who will appear on national TV in the Argos advert this weekend, including in high-profile spots during ITV’s Catchphrase and Channel 4’s Come Dine with Me.

The advert, which celebrates Argos’s commitment to super speedy delivery, features a futuristic rocket-powered super-sleigh.

As it readies to take off on its mission across the country an elf spots that a child’s long-awaited Christmas present, a Teksta voice-recognition robotic puppy, has lost its way from the sleigh.

The quick-thinking elf scans it in to reveal its intended recipient on-screen – seven-year-old Harry – whose family’s gifts are departing from gate nine.

This leads to a blockbuster-style chase across the distribution centre in which the elf pulls out all the stops to ensure the robotic puppy makes it to Harry in time for Christmas.

Gary Kibble, marketing director at Argos, said: “We’re really proud to make Argos the first UK retailer to personalise its Christmas advert across both TV and social media – and we can’t wait to see Harry become part of the action.”

Those not lucky enough to win a place in the TV advert can still have the chance to see their child’s face in a personalised social media version of the advert which they can share with loved ones.

They simply need to upload their child’s photo on the Argos Facebook or Twitter sites, or send a direct message, and include the hashtag #ReadyForTakeOff.
