Tony Blair's reshuffle is doing away with the position of Lord Chancellor, a job which has existed for 1,400 years. But here's your chance to have a memento.
Although Lord Falconer is holding the position initially, he will not do be doing the full role which has made the job so controversial.
In fact one of Lord Falconer's main tasks will be to do away with the post altogether - ending a history which goes back to the first holder of the job, Angmendus in the year 605.
Lord Irvine will thus be the last person to hold the position properly. For many people, he will be remembered for the outrage which surrounded the redecoration of his official residence at Westminster in 1998.
Hand-made wallpaper, in the style of the Pugin original, cost £59,000. Lord Irvine justified the expense at the time by saying it was for a "noble cause", adding: "We are not talking about something down at the DIY store that might collapse after a year or so."
Now, just five years later, everything has changed. Without a Lord Chancellor, there is no need for him to have an official residence. So this is your chance to have a keepsake of the nation's history.
