The UK Independence Party has hailed the recruitment of a man with family connections to Guy Fawkes - with leader Nigel Farage saying it shows "the blood of rebellion still runs in his veins".
Mr Farage said retired headteacher Philip Fawkes was the "10 times great grandson" of the leader of the 1605 Gunpowder Plot and the party speculated that he might one day get to the Commons by legitimate means.
A spokeswoman said that in fact he was not directly descended but shared a common ancestor in the Catholic plotter's 15th century great great grandfather.
Guy Fawkes plotted to kill King James I, MPs and Lords at the State Opening of Parliament by detonating 36 barrels of gunpowder stashed around the Palace of Westminster was foiled.
"Was Guy Fawkes the last man to enter Westminster with honest intentions?" Mr Farage wrote on Twitter.
"Ukip has its own Mr Fawkes, sharing the same lineage."
He later added: "I'm absolutely delighted to welcome Philip aboard into our ever-expanding team.
"It is obvious that the blood of rebellion still runs in his veins".
