Pakistan 363 (Babar 68*, Shafiq 59, Shadab 52, Azhar 50, Stokes 3-73, Anderson 3-82) and 66 for 1 (Sohail 39*) beat England 184 (Cook 70, Abbas 4-23, Hasan 4-51) and 242 (Root 68, Butler 67, Bees 57, Amir 4-36, Abbas 4-41) by 9 wickets
London: England succumbed to a miserable nine-wicket defeat by brilliant Pakistan on the fourth day of the first Test at Lord's.
Optimism provided by Jos Buttler and Dom Bess on the third evening was dashed by the eighth delivery of the day, when Buttler was trapped lbw by Mohammad Abbas for 67.
That began a collapse of four wickets for six runs, leaving England 242 all out and Pakistan chasing only 64 to win.
Although James Anderson bowled Azhar Ali in the third over, Haris Sohail and Imam-ul-Haq shared an unbroken stand of 54 that had victory sealed 90 minutes into the day.
Following a winter when they did not win in seven Tests in Australia and New Zealand, this is an awful result for England, who spoke before this match of returning to winning ways and developing skills that will make them more competitive in foreign conditions.
Instead, they have lost the first Test of a home summer for the first time in 23 years.
For Pakistan, this is a wonderful result, their thorough preparation leading to a superiority over the hosts in all aspects of the game.
They will have the opportunity to seal their first series win in England since 1996 when the second and final Test begins at Headingley on Friday.
