well, according to the letter of the law, they should do so.
I don't see which bit of the law says the police need to give permission. Neither do I see which bit of the law says that they have a different rule for 'sole protestors' as opposed to groups. The full text is here:
http://www.opsi.gov.uk/ACTS/acts2005/20050015.htm (see sections 132 to 138).
The police seem to have various 'get-out clauses':
Serious Organised Crime and Police Act 2005
section 134 (Authorisation of demonstrations in designated area)
part 3:
(3) In giving authorisation, the Commissioner may impose on the persons organising or taking part in the demonstration such conditions specified in the authorisation and relating to the demonstration as in the Commissioner's reasonable opinion are necessary for the purpose of preventing any of the following-
(a) hindrance to any person wishing to enter or leave the Palace of Westminster,
(b) hindrance to the proper operation of Parliament,
(c) serious public disorder,
(d) serious damage to property,
(e) disruption to the life of the community,
(f) a security risk in any part of the designated area,
(g) risk to the safety of members of the public (including any taking part in the demonstration).

The police are also allowed to specify:
(a) the place where the demonstration may, or may not, be carried on,
(b) the times at which it may be carried on,
(c) the period during which it may be carried on,
(d) the number of persons who may take part in it,
(e) the number and size of banners or placards used,
(f) maximum permissible noise levels.
So maybe they could legally get away with specifying:
...a spot 1km away from parliament square, of a one metre square
...a very sort time period (eg 1 minute)
...one person (obviously not a problem for a 'sole protestor')
...no placards
...complete silence
Which would more or less be equivalent to not giving permission at all surely?
