An estimate of the number of visitor stickers used on the Parliamentary Estate in each of the last 12 months based on number of visitors counted through search points is in the following table.
| Note: |
These figures are based on numbers provided by the Metropolitan Police using counting devices at search points. The counting device at Norman Porch is proving unreliable due to an ongoing technical fault, so Visitors Tour figures have been used instead. There may be a slight under-estimate due to Members or Peers guests using Norman Porch who will not be included in the Visitor Tour figures.
