The US–UK Extradition Treaty 2003 was first sent to the US Senate for approval in April 2004. But another component of the controversy noted above was a result of the delay of the US in ratifying it into US law. Baroness Scotland, British Minister of State for the Criminal Justice System at the Home Office, travelled to the US on Thursday 13 July 2006 to address this problem. This move was prompted by political criticism of the Extradition Act 2003 within the UK and an opposition proposal to amend the Act in the House of Lords. It also coincided with public disquiet at the case of the NatWest Three who were extradited on the same date. This meant the NatWest three were extradited to the US under the US–UK Extradition Treaty 2003, even though that treaty had not been ratified in the US.
