Why do Pride flags fly over British police stations, prisons and other government buildings?
<p>Insofar as this question may have a legal answer, by what provisions or instruments are they flown or allowed to be flown? Who would have the power to decide what flags are flown over such institutions? For example, the Daniel Quasar “progress pride” flag flies over HMP Pentonville. What provisions might govern such a practise?</p>

<blockquote>
<p>... Some flags require formal consent (permission) from the local
planning authority, whereas others like the Union Flag do not. The
detailed controls over flag flying are set out in detailed regulations
(see links below). ...</p>
<p>All flag flying is subject to some standard conditions</p>
<p>...</p>
<p>Subject to compliance with the standard conditions, there are 3
categories of flag:</p>
<p>(a) flags which can be flown without consent of the local planning
authority</p>
<p>(b) flags which do not need consent provided they comply with further
restrictions (referred to as “deemed consent” in the Regulations)</p>
<p>(c) flags which require consent (“express consent”)</p>
<p>...</p>
<p>(b) Flags which do not require consent provided they comply with
certain restrictions [include for example] ... the Rainbow flag (6 horizontal equal stripes
of red, orange, yellow, green, blue and violet).</p>
<p>...</p>
<p>The regulations governing the flying of flags in England are set out
in the Town and Country Planning (Control of Advertisements)
Regulations 2007 (as amended in 2012 and in 2021).</p>
<p>These regulations, including relevant amendments to flying of flags,
can be viewed on the government legislation website:</p>
