Royal Ascot weather forecast: day-by-day Met Office predictions for muggy week of racing

It's set to be another memorable year at Royal Ascot as the horse racing action gets underway on Tuesday.

The first meeting of the iconic races since the passing of Her Majesty Queen Elizbeth II last year and it is also set to be the final bow for famous jockey Frankie Dettori.

There's of course a looming worry for event organisers that animal rights protestors may try and disrupt proceedings after drama at the Grand National earlier this year.

For many, Royal Ascot provides the perfect chance to don some finery and enjoy a day out in the British sun.
