Jack Straw in the context of "Canvassing"

The Lords Commissioners are privy counsellors appointed by the monarch of the United Kingdom to exercise, on his or her behalf, certain functions relating to Parliament which would otherwise require the monarch's attendance at the Palace of Westminster. These include the opening and prorogation of Parliament, the confirmation of a newly elected Speaker of the House of Commons and the granting of royal assent. The Lords Commissioners are collectively known as the Royal Commission. The Royal Commission includes at least three—and usually five—Lords Commissioners. In current practice, the Lords Commissioners usually include the Lord Chancellor, the Archbishop of Canterbury (who is named but usually does not participate), the leaders of the three major parties in the House of Lords, the convenor of the House of Lords Crossbenchers and (since 2007) the Lord Speaker. Occasionally there are substitutions (such as deputy party leaders) if the normal commissioners are unavailable.

The Lord Chancellor serves as the most senior Lord Commissioner after the Archbishop of Canterbury, who in modern times never participates in the Commission. Traditionally the Lord Chancellor took part in the ceremony and presided over the Royal Commission. However, since the 2007 appointment of Jack Straw, a member of the House of Commons, as Lord Chancellor the person in that office does not participate in Royal Commissions, much like the Archbishop of Canterbury. In this case, the Leader of the House of Lords performs the duties of the Lord Chancellor, with the Lord Speaker of the House of Lords serving as a Lord Commissioner. Exceptions to this procedure were seen in 2009 and 2019, when royal approbation was declared to the elections of John Bercow and Lindsay Hoyle as Commons speaker. On these occasions the lord chancellor, respectively Jack Straw and Robert Buckland, performed this function personally and the Lord Speaker did not serve as a Lord Commissioner.

Stephen Adrian Lawrence (13 September 1974 – 22 April 1993) was an 18-year-old black British student from Woolwich, southeast London, who was murdered in a racially motivated attack while waiting for a bus on Well Hall Road in Eltham, on the evening of 22 April 1993. The case became a cause célèbre; its fallout included changes of attitudes on racism and the police, and to the law and police practice. It also led to the partial revocation of the rule against double jeopardy. Two of the perpetrators were convicted of murder on 3 January 2012.

After the initial investigation, five suspects were arrested but, at the time, not charged; a private prosecution subsequently initiated by Lawrence's family failed to secure convictions for any of the accused. It was suggested during the investigation that Lawrence was killed because he was black, and that the handling of the case by the Metropolitan Police Service (MPS) and Crown Prosecution Service (CPS) was affected by issues of race. A 1998 public inquiry, headed by Sir William Macpherson, concluded that the original MPS investigation was incompetent and that the force was institutionally racist. It also recommended that the double jeopardy rule should be repealed in murder cases to allow a retrial upon new and compelling evidence: this was effected in 2005 upon enactment of the Criminal Justice Act 2003. The publication in 1999 of the resulting Macpherson Report has been called "one of the most important moments in the modern history of criminal justice in Britain". Jack Straw said that ordering the inquiry was the most important decision he made during his tenure as home secretary from 1997 to 2001. In 2010, the Lawrence case was said to be "one of the highest-profile unsolved racially motivated murders".
