As the nation’s new Prime Minister, Keir Starner, made his first official speech on Downing Street this afternoon, his doting wife stunned in a Labour red midi dress before walking arm in arm into number 10. And our fashion experts have found the exact match online.

Following a landslide victory for Labour, Lady Victoria Starmer took her first steps on the street as the Prime Minister’s wife wearing a pretty split-shoulder dress from fashion brand ME+EM. The mum-of-two stepped out in the retailer’s Contrast Stitch Midi Dress , which retails at £275.

The poppy red dress is made from a crease-resistant fabric, which may be why NHS occupational therapist Victoria chose it for the important occasion. It makes it a great choice for all-day wear, or those days you may be getting important photos taken, such as a wedding or, of course, entering Downing Street.

The dress boasts a comfortable elasticated waistline which the brand says gives it a ‘flattering’ fit, while pockets make it perfectly practical, without looking bulky. We love the fact you can adjust the finish of the neckline with the hook and eye fastening, as well as the short sleeves with split detail which give the dress some movement, while providing light coverage of the upper arms.

The dress falls to a midi length , but online, is featured on a 5’10” tall model, so shorter shoppers may find the length on the longer side. It comes in sizes 6-18, with ME+EM recommending you take your usual size. It looks great with heels, with the 49-year-old opting for a pair of slingbacks, which elevated the look.

If you haven't got a big budget to spend and looking for a more affordable alternative we've found 3 high-street red dresses for you so you can get the look for less, selected by our Fashion Editor. Including this must-have £40 red broderie hem shift dress from River Island.

Mrs Starmer isn’t the only one who loves a split-sleeve detail, though, as it’s a style Cat Deeley has also sported a number of times in recent weeks, including this Cream Floral Ruched Midi Dress from Mint Velvet, which features a pretty rose print design. It would have been another great choice for Victoria’s Downing Street entrance.

And at the exit polls last night, we also spotted Angela Rayner donning red for her party, but it was actually her earrings that grabbed our attention. While it's not been officially confirmed, we think they could be these Enamel Oval Hoop, from Whistles, which cost £35.

Though she’s been rarely seen throughout the Prime Minister’s campaign, Lady Victoria Starmer is set to be one of the most stylish residents of 10 Downing Street. And we can’t wait to see what outfit she picks for her next event. If you fancy this poppy red dress from ME+EM for your own wardrobe, you can buy it here .
