The Duke of Edinburgh was laid to rest on Saturday 17 April with only 30 royals attending the service due to coronavirus restrictions.
Among them was the Countess Mountbatten of Burma, Penelope Knatchbull, who was always one of the closest companions of both the Queen and Prince Philip.

Known informally as Penny, the Countess is the only daughter of butcher-turned-businessman Reginald Eastwood and she became close to the royal family through her marriage to Norton Knatchbull, 3rd Earl of Mountbatten of Burma.

However, HELLO! understands that the real reason behind her attendance is to stand as a representative for her husband, who could no longer attend the funeral due to ill health.
The Earl is the grandson of Admiral of the Fleet Louis Francis Albert Victor Nicholas Mountbatten, 1st Earl Mountbatten of Burma, a British Royal Navy officer and statesman and uncle of Prince Philip.

Penelope was an immediate hit with the royals, but particularly impressed the Queen and Philip when she was first introduced by Norton Knatchbull in 1975.

Despite an age difference of more than 30 years, a shared love of the outdoors allowed their friendship to flourish, which only strengthened after Philip taught the Countess to drive carriages in 1994.
The Queen and the four children she shared with her husband of 73 years – Prince Charles, Princess Anne, Prince Andrew and Prince Edward – led the royal family in paying their respects at St George's Chapel.

They celebrated Prince Philip's incredible life and legacy at Saturday's service. The Duke died peacefully aged 99 last Friday 9 April at home in Windsor Castle.
