The group – which includes Tory grandee Lord Heseltine – also told the watchdog that they had “concerns about the motivation for bringing this prosecution”.
Tory MP Simon Hart, a former chief executive of the Countryside Alliance, said last night that it was “very sad” that a branch which daily cared for sick and injured animals was potentially closing down weeks after the prosecution.
He told The Daily Telegraph: “It is very sad that pets are going uncared for due to lack of funds at the same time as the Charity spends a third of a million on a case that will not save the life of a single fox.
“There is a huge difference between being an animal welfare organisation, which the RSPCA used to be famous for, and an animal rights one, which is what the society is fast becoming.”
The RSPCA declined to say whether its national office, which last year received £100million in donations, would intervene to stop the Preston branch from closing.
