The Defence Secretary and Scottish Secretary have been involved in ceremonial guard duties as the Queen lies in state.
Ben Wallace and Alister Jack took part in the vigil at Westminster Hall on Thursday.
Both men are members of the Royal Company of Archers, which functions as the sovereign's bodyguard in Scotland.
The men, dressed in their dark uniforms, stood side by side at one end of the Queen's coffin.
After the Queen's death at Balmoral in Scotland last week, Mr Wallace said she had "dedicated her life to serving her nation".
Speaking about the Queen after her death was announced, Mr Jack stated: "Her long reign was defined by hard work and dedicated public service, earning her the respect and devotion of her citizens."
