Following a surprisingly good Valencia, Formula One moves on to the UK, where the paddock is facing a rather wet welcome. The forecasts are not great for the weekend, but we know that the sport can still deliver, and this is where it all begins. Two practice sessions are on the cards today, with ninety minutes apiece for teams to start gathering their data. Pirelli have also offered up some experimental hard tyre compounds - extra sets of tyres - for the teams to evaluate on their behalf. There may be some interesting things to see this damp Friday!
