Police said the scale of the funeral will be unprecedented, with two minutes of silence to be observed by police throughout the country. Palmer's coffin lay overnight in a chapel at Parliament after special permission was granted by the Queen. Masood killed four other victims as he rammed pedestrians on Westminster Bridge with a rented SUV.
