According to The Guardian, his children, Emma, Justine and Paul, in a statement announcing his death said: "Gruff, elegant, twinkly, and always dignified, he is celebrated by all who knew him and loved him, and everyone who enjoyed his work". "We are immensely grateful to the team at Denville Hall for the tender care they gave during his last weeks".
They said he was part of the team that raised the Tudor warship the Mary Rose, which sank off England's south coast in 1545.
Hardy was a prolific British actor of both stage and screen, with many well-known and memorable roles under his belt before he joined the Potter franchise as the weak and ambitious Minister for Magic Cornelius Fudge.
Between 1978 and 1990, Hardy played the eccentric veterinarian Siegfried Farnon in "All Creatures Great and Small", a popular TV series based on James Herriot's books about rural life in the Yorkshire Dales.

However, it is hard to say which doctor's report is true, so it is still not sure whether Dilip Kumar is critical or not. People were describing his condition as not stable and not critical either but this should get fans anxious .
A familiar face in households across the country, Hardy's other roles included Tite Barnacle in Little Dorrit (2008) and Arthur Brooke in Middlemarch (1994).
In 1981, he was awarded Commander of the Order of the British Empire (CBE) for his services to acting, but that was by no means his only passion.
