The Wimbledon tennis tournament is likely to be hit by frequent rain as June's poor weather continues, forecasters have warned.
There will be a sunny start to the first day's play on Monday, but wet weather will persist through both weeks of the event.
Organisers will be cheered by predictions that the rain will be interspersed with sunny spells.
A Met Office spokesman said: "What we are likely to see is a mix of the weather we have seen recently - on the dry side and relatively sunny with one or two rogue showers around, but interspersed with periods of cooler and wetter weather."
