Those addicted to the weekly Prime Minister's Questions in the House of Commons will have to adjust their TV viewing habits from today. Under the package of reforms of parliamentary business arrangements Mr Blair will rise to detail his engagements for the day at noon, UK time, instead of the traditional 3pm. This change has been made for two reasons. First, all House of Commons procedure has been moved forward by several hours so that an MP's working day will in future more nearly resemble that of the rest of the population. Second, the government believes that Prime Minister's Questions will get more attention from the public if it is being shown live at around lunch time and will also catch the headlines and editorials of evening newspapers.
