Lady Helen Wogan, the wife of late TV veteran Sir Terry Wogan, has died after a "fantastic life", her son has announced.

Mark Wogan said he hoped she and his father, who died from cancer in January 2016 at the age of 77, were "sharing a vodka martini and hoping we don't make too much of fuss".

Announcing the news on Instagram, Mr. Wogan shared a video featuring pictures of his mother and father over the years, describing Lady Helen as "the epitome of style and grace".

"Our beautiful mum left us last night after a fantastic life," he wrote.

"From a young Irish rose to Lady Wogan, she was the epitome of style and grace.

"A mother, grandmother, and wife, with love and kindness at her core. A strength and a belief that saw her through many of life's trials.

"A sense of humor and a turn of phrase that would have you in fits of laughter.

"A proper lady in every sense of the word."

He added: "Her and dad are hopefully sharing a vodka martini and hoping we don't make too much of a fuss."

Fearne Cotton, Jamie Redknapp, Julia Bradbury, Laura Whitmore, and Tess Daly were among the celebrities who paid tribute to the post.

"Sending love matey. God bless ya all," Ronan Keating said.

Jeremy Clarkson wrote: "Horrible when it happens. Thinking of you."

Eamonn Holmes said: "What a woman and what a couple."

Sir Terry and Lady Helen, who were both born in Ireland, were married for more than 40 years. They spent much of their lives in the Buckinghamshire village of Taplow.

They shared four children and five grandchildren.

Sir Terry, the Limerick-born broadcaster, was known for his chat shows, Children In Need and his often blistering commentary on the Eurovision Song Contest.

As well as his long-running Radio 2 breakfast show, he also fronted the long-running panel show Blankety Blank.
