The campaign organisation Fathers4Justice (F4J) has said it believes one of its members tried to write 'help' on a portrait of the Queen in Westminster Abbey.
Campaign Director Jolly Stanesby said the member, who is allegedly a father from Doncaster, had "felt he had nothing to lose by appealing directly to the Queen for help".
We understand that a desperate father belonging to Fathers4Justice has attempted to write the word 'help' on a portrait of the Queen in Westminster Abbey at lunchtime.
The father...was trying to petition the Queen for help before Father's Day on Sunday.
Up to 4 million children will be without a father this Father's Day.
[He] has lost all contact with his children and felt he had nothing to lose by appealing directly to the Queen for help by spraying his plea onto her portrait."
