London bridges lit up in purple in memory of Queen Elizabeth

Nine bridges spanning the River Thames in central London have been illuminated in purple in memory of Queen Elizabeth II.

The Queen often wore purple in her later years.

On Thursday night, the seven arches of Westminster Bridge, at the foot of Big Ben, were lit up in vivid purple.

Tower Bridge, a popular tourist spot, was tinged with deep purple.

London Bridge was also decorated in shades of purple. "Operation London Bridge" was the codename for the Queen's funeral plan.

People formed a long line along the river to pay their final tribute to the Queen, who is lying in state at Westminster Hall.

A woman, who had been waiting for around five hours with her family, said she was impressed by the spectacular view. She said it demonstrated the nation's unity in mourning the death of the Queen.

The nighttime illumination will continue until Monday, when the Queen's state funeral will be held.
