If you've booked a holiday to Albania this summer, you might want to think twice before heading for a dip in the sea.

A new report has revealed Europe's dirtiest beaches, where the water quality is rated as 'poor'.

Albania tops the list for the worst water quality in Europe, with a whopping 23 per cent of coastal swimming spots getting a poor rating.

That is over three times the proportion in the second worst nation, Estonia, where 6.7 per cent of beaches were ranked as poor.

To make matters worse, just 16 per cent of Albanian beaches were given an 'excellent' rating, while 38 per cent are considered 'good'.
