LONDON (Reuters) - Britain's Queen Elizabeth carried out her first official engagement on Tuesday since spending a night in hospital and being ordered to rest by her doctors.

The 95-year-old queen, the world's oldest and longest-reigning monarch, stayed overnight at London's King Edward VII private hospital last Wednesday after undergoing "preliminary investigations" for an unspecified but not COVID-19 related ailment.
