An accountant who claims he fell into a deep depression after slipping on a grape outside Marks & Spencer began his High Court battle with the supermarket yesterday.

Alexander Martin-Sklan, of Golders Green Road, Golders Green, is suing M&S for more than £300,000 after he allegedly slipped on the grape at the company's store in Finchley Road in 2004.

The 55-year-old ruptured a tendon in his leg and claims that his business suffered after the injury caused him to become depressed and lose confidence.

Mr Martin-Sklan represented himself through written submissions to the court, which stated: "The claimant, upon conclusion of his shopping in the store and having just passed the fruit and vegetable section, exited into the car park.

"Walking on to the ramp outside and while pushing the trolley down the slope, a car appeared to his left.

"That car was driving at speed and the claimant was startled and compelled to stop suddenly - and as he did so his right foot slipped outward and he fell awkwardly.

"He ripped his quadriceps tendon as a result. A piece of stepped-upon fruit was found on his right shoe."

He said his injuries had stopped him playing tennis and football and going on skiing holidays.

He is claiming a total of £315,815 in damages.

M&S, represented by barrister James Aldridge, has denied responsibility for Mr Martin-Sklan's injury.

Mr Aldridge pointed out that the claimant was wearing sandals and may have already picked up the slippery substance which caused him to slip before entering the store.

He argued that it had all been an "unfortunate accident".

The hearing is expected to end today.
