Many fathers don't have the money or emotional strength for lengthy court battles which is why high profile lobbies are still vital, according to F4J
founder Matt O'Connor.
It is believed to be linked to F4J
founder Matt O'Connor standing for mayor of London for the English Democrats.
Protesters, some dressed as super-heroes, would then hang F4J
banners and mount a sit-in protest.
The incident was the latest in a slew of high-profile publicity stunts from F4J
, who are demanding the courts give fathers equal rights of access to children in divorce settlements.
A grandfather from Bristol who has been on hunger strike for a week was also at the event to help raise awareness for the F4J
Phil Davies, Welsh co-ordinator of F4J
, said fathers from as far afield as London, Bristol, Liverpool, and Manchester had travelled to the city for the protest.
But the superhero gimmick closely mirrors the hallmarks of F4J
which has staged controversial high-profile demonstrations to campaign for more rights for divorced and separated fathers.
When it was alleged that F4J
members hatched a plot to kidnap Tony Blair's youngest son, Leo, in January this year, Matt O'Connor said the group was to be disbanded.
On January 18 Mr O'Connor announced he was disbanding F4J
after details of the alleged plot to kidnap Leo Blair were published in The Sun.
Former Liverpool F4J
branch member Peter Molloy, from Childwall, is among the men setting up the Equal Parenting Alliance, aimed at trying to change family law to recognise fathers' rights.
sympathisers who were present during the conversation were later visited by police and warned they could be shot at future stunts.
He and fellow F4J
member Andrew Benn collected signatures for a petition condemning family law.
