One of the most outspoken members of the US Republican Party over the Epstein files has told the BBC he is "not satisfied until the survivors are satisfied".

Thomas Massie, a congressman representing Kentucky, told the Newsnight programme: "Men need to be perp-walked in handcuffs to the jail, and until we see that here in this country... we don't have a system of justice that's working."

Massie has criticised the Department of Justice (DOJ) for the number of files that it redacted or withheld after it complied with a law - co-written by Massie - to release all its material.

DOJ officials have said they have released all of their files other than certain items permitted to be exempt.

In contrast with the situation in the US, the UK was "the only place that we're seeing arrests", Massie said. He said it was "ironic that [the US] thought we could have more justice by becoming independent from Britain".
