TNS Superpanel is a division of the United Kingdom based global market information group Taylor Nelson Sofres , which analyses the British grocery sector. Every month it publishes market share data for the United Kingdom grocery market for the preceding twelve week period, based on till-roll data from a representative cross-section of 15,000 households. This information is widely publicised in the business and general media in the United Kingdom, and is closely watched by retail analysts.

Partial results for the 12 weeks to 27 March 2005:

• Tesco 29.5%
• ASDA 16.7%
• Sainsbury's 15.9%
• Morrisons 12.1% (including Safeway)

For the 12 weeks to 2 January 2005 the results were as follows:

• Tesco 29.0%
• ASDA 17.1%
• Sainsbury's 15.9%
• Morrisons 12.5% (including Safeway)
• Somerfield 5.5%
• Co-op 5.0%
• Waitrose 3.6%
• Aldi 2.3%
• Iceland 2.1%
• Lidl 1.8%
• Netto 0.7%
• Budgens 0.4%

Marks and Spencer is omitted by TNS for some reason. It would probably rank just behind the Co-op.
