Our thanks goes to the vulture-eyed Register reader who sent us this snapshot after a late night shopping trip to his local supermarket. Mulling the vast and colourful array of toilet cleaners on offer, he spotted this germ killer - and could have sworn he'd spotted the logo somewhere before.

A spokesman for mobile phone giant O2 - which is never too keen to seen its brand diluted in any way - told us that they did come across this sort of thing "from time to time" and that alleged cases of trademark infringement are examined on a "case by case basis".

Of course, O2 and Tesco are best buddies thanks to their joint venture, Tesco Mobile.

Even so, asked whether O2 had been in touch with Tesco over the logo, an O2 spokesman said "no" but said they would be "loo-king into it". ®
