In January 2020, a new painted portrait of Lynn was unveiled at the Royal Albert Hall in connection with the 75th anniversary of the peace in 1945. The portrait is painted by Ross Kolby and was unveiled by Lynn's daughter Virginia Lewis-Jones and Britain's Got Talent winner Colin Thackery. The painting will be on permanent display at the venue where Lynn performed 52 times from 1937 to 2006. The documentary film Dame Vera Lynn – The Voice of a Nation premiered at the unveiling ceremony at the Hall and tells the story of 'The Forces' Sweetheart' and Kolby's portrait.
On 5 April 2020 the song "We'll Meet Again" was echoed by Queen Elizabeth II in a television address she delivered addressing the COVID-19 pandemic. For the 75th anniversary of VE Day, Lynn and Katherine Jenkins duetted virtually (Jenkins singing next to a hologram) at the Royal Albert Hall, which was empty due to the COVID-19 pandemic.
Vera Lynn died on 18 June 2020 at her home in East Sussex aged 103. Tributes to Lynn were led by the Royal Family, with Queen Elizabeth II sending private condolences to Lynn's family and Clarence House issuing tributes from Prince Charles and the Duchess of Cornwall. The Prime Minister, Boris Johnson, and Leader of the Opposition, Sir Keir Starmer, also led with tributes in Parliament, while musicians like Sir Paul McCartney and Katherine Jenkins and public figures like Captain Tom Moore discussed her profound impact. On the day of her death, regular programming on the BBC was stopped in order to air tributes to the singer. The Band of the Coldstream Guards convened the same day to play her song "We'll Meet Again". After Lynn's death, Jenkins began campaigning to erect a statue of her by the White Cliffs of Dover, a location referenced in another of her famous songs.
Lynn was given a military funeral, which was held on 10 July 2020 in East Sussex. The procession made its way from her home in Ditchling to the Woodvale Crematorium in Brighton; it was widely attended by the public. Ditchling was decorated with poppies, a symbol of military remembrance. Ahead of the funeral, the White Cliffs of Dover had images of Lynn projected onto them, as "We'll Meet Again" was being played across the English Channel. Her cortege was accompanied by members of the Royal Air Force, the British Army, the Royal Navy, and the Royal British Legion, as well as the Battle of Britain Spitfire flypast, which followed the cortege and passed over Ditchling three times (10 July 2020 was the 80th anniversary of the start of the Battle of Britain). Her coffin was draped in a Union Flag with a wreath. At the family service at the Woodvale Crematorium chapel, she was serenaded by a Royal Marine bugler. Her family have said a public memorial service will be organised for some time in the future.
