Protesters from paternal rights group Fathers 4 Justice stormed BBC TV studios last night to hold up the UK National Lottery draw.
The broadcast was interrupted for several minutes before the £17 million (US$32 million) Superdraw jackpot got underway.
Protesters unfurled a banner proclaiming: 'Family Law Lotto. Next time it could be you.'
Although the group officially disbanded in January after some members were accused of plotting to kidnap prime minister Tony Blair's youngest son, Leo, a spokesman signaled 'the dramatic return' of Fathers 4 Justice.
'The lottery is a metaphor for what can happen to any parent, mother or father, and their children, at the hands of the secret family courts,' Graham Manson said.
'It's our duty to warn parents about what is happening and send them this message: don't play family law lotto — don't gamble with your kids.'
Mr Manson said Ray Barry and Nadine Radford — among six protesters who entered the BBC's premises — carried out the protest to highlight 'the lottery faced by people every day in the family law courts.'
Real Fathers 4 Justice is a splinter group of a defunct group that campaigned for changes to child-custody laws.
The National Lottery draw attracts about 8.5 million viewers.
Has this ever happened in the US or Canada? There are several US games I wouldn't mind interrupting.
