British National Party leader Nick Griffin will not face criminal charges for posting the address of a gay couple on Twitter and encouraging BNP supporters to demonstrate outside their home. Michael Black and John Morgan won a court case in October against a Christian B&B owner who denied them a room in 2010.

In response to the ruling, Griffin tweeted: "A British Justice team will come up to [their Huntington address] & give you [the couple] a … bit of drama by way of reminding you that an English couple's home is their castle. Say No to heterophobia!" An earlier message read: "If anyone can give us address of the 2 bullying 'gay' activists who've won case v Christian B&B owners, we'll hold demo … for rights of all home owners, gays included, to rent or not rent rooms to whomsoever they wish".

After complaints that he had incited violence against the couple, an investigation was launched by Cambridgeshire police but no further action will now be taken. A police spokesperson said: "Following a police investigation and advice from the Crown Prosecution Service no criminal offences were identified."

Black told BBC News that the couple were not overly concerned about Griffin's tweets. "In the end we decided not to make a formal complaint," he said. "The tweet was only up for a short time, it did not give a specific time... and nobody came."

Susanne Wilkinson, who refused to let Black and Morgan stay in a room with a double bed at her Cookham guest house in March 2010, has appealed against the original court ruling. The case will be heard between April and June next year.

Black said: "I understand their barrister is trying to get [the case] dealt with early and get it put with the Cornish one at the Supreme Court.

"Of course there is the possibility of being overturned but we are pretty confident that we will win."
