Sir Terry Wogan's wife Lady Helen has died, her son Mark confirmed in a heartbreaking post on Instagram. 

He shared a black and white image of his parents on the social media platform with the caption: 'Lady Helen Wogan - 1936-2024.'

Lady Helen was married to the late broadcaster for more than 50 years before his death from cancer in January 2016. 

The couple shared four children and five grandchildren together.

Their son Mark paid tribute to a 'beautiful' mother and grandmother as he announced his mother's death on Thursday.

He wrote: 'Our beautiful Mum left us last night after a fantastic life. 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 humour and a turn of phrase that would have you in fits of laughter.

'A proper lady in every sense of the word. Her and Dad are hopefully sharing a vodka martini and hoping we don't make too much of fuss. We love you Mum, now and forever.'

Celebrities shared their condolences as they led the tributes to Lady Helen in the comments section.
