Janman was subsequently quoted by journalist Judy Jones in The Daily Telegraph as saying that: "if you look at the lack of immigration control in the past, then yes, Britain has become the dustbin of the world". He added that there was a need to offer voluntary repatriation to some members of ethnic minorities settled in the UK, which did not wish to integrate with the indigenous population.^{[citation needed]}
