has announced her retirement from after 36 years.
Kay made a final statement on her last ever show, confirming to viewers: "From a standing start to one of the most recognised and valued brands in global news, it's been an honour and privilege to work with some of the best and hardest working teams in the business.
"News by its very nature is often devastating and together we've covered so many life-changing events - from the tragic death of Diana, the shocking terror attack of 9/11; the Asian Tsunami; the Concorde air disaster.
"But we've also enjoyed some wonderful high notes too, haven't we - the thrill of London winning the chance to host the 2012 Olympics; a plethora of royal weddings; jubilees and who can forget days and days and DAYS waiting for royal babies to arrive at the Lindo Wing."
An emotional Kay went on: "But after over a million minutes of live TV news - more than anyone else in the world - its time for me to indulge in some of my other passions - including my love for travel."
The veteran presenter went on: "So, after covering 12 separate general elections - including Sir Keir Starmer's victory last year - I am retiring from Sky News - let politicians of every party just rejoice at that news!
"Thank you for waking up and tuning in every morning. I can't tell you how much I have appreciated your support over the last three and a half decades: You're awesome.
"I will post more on my social media and hope to see you around. Please keep in touch."
As well as a keen traveller, Kay is a fan of mountaineering - and once conquered the Three Peaks Challenge.
She joined Sky News way back in 1989, winning a BAFTA award for her coverage of the 9/11 terrorist attack.
But in December 2020 Kay was suspended from her show for six months after she breached London's tier 2 coronavirus restrictions. She returned in June 2021, telling viewers: "It's great to be back," before she launched into the headlines of the day without addressing the ban.
