Most graffiti is ugly to look at and a lot of it consists of messages ranging from the incomprehensible to the reprehensible.

But a minority of messages are genuinely pleasing to the eye and some have uplifting statements to make.

There have been witty slogans written on builders' hoardings in Brighton and Hove while one reader was delighted with love poetry in the North Laine.

The problem with graffiti, good or bad, is that it's in the wrong place. It defiles clean walls and is a form of vandalism.

Left unchecked, it quickly proliferates and can lead to city centres becoming unpleasant and unkempt.

There are official spaces where graffiti artists can go. Let them write their funny and clever messages there rather than defacing other parts of the city.
