England, after losing the toss, were 39 for one against Pakistan at tea on the first day of the fourth and final Test at Lord's here on Thursday. Alastair Cook was 10 not out and Jonathan Trott eight not out on an opening day marred by bad weather. Rain meant no play was possible before lunch and only 12.3 overs had been bowled when the umpires took the players off for bad light. Although the Lord's floodlights were switched on, it appeared players were struggling to see the red ball out of an otherwise dark background. England lead the series 2-1.
