Meghan Markle and Prince Harry are back in the UK, but only for a few hours. Still, they didn't miss an opportunity to make an impact while Meghan delivered the keynote speech at the One Young World summit in Manchester.

It was the activist's first public appearance in the UK since stepping down as a senior royal, and the couple's first in a series of appearances this week. They travelled to the venue by train and next, they will travel to the Invictus Games.

She addressed the young crowd by saying: "You are the future... you are the present... You are the ones driving the positive and necessary change across the globe now, in this very moment. And for that I am so grateful to be in your company today."

She recalled being asked to be a One Young World representative in 2014 as a "pinch me moment", adding that even then she wasn't sure she belonged alongside the people in the room.

"And I want to make that point because often times I speak to young girls about the years ahead. About what you will do, about what you will have to adopt to fix from previous generations and also what legacy you will leave.

"Too often in that, we neglect the point - you are doing it now. You, here, in this present moment, this is where it is all beginning."

Meghan opted for head-to-toe red, a striking outfit choice that contrasts with the beachy neutrals she's often spotted in in her Montecito home.

She chose a flowy red blouse from sustainable brand Another Tomorrow, costing €543, featuring a high neckline, concealed buttons, long sleeves and an elegant attached scarf that drapes over the shoulders. She wore it looped around her neck and falling over one shoulder.

She paired this with the brand's matching Classic Trousers, which are a straight-leg design and cost €593. She finished her look with a pair of strappy pointed toed stiletto heels, with an open cutwork toe and T-bar ankle strap.

To add some glamour to her look, she wore a pair of chunky gold hoop earrings, and a smattering of rings on her fingers. Her long wavy hair was pulled back into a sleek ponytail, while her makeup was fresh and dewy, with a glossy lip and her signature smokey eyes.
