The left-arm spinner, who won the man-of-match award, took five for 81 in the second innings and nine for 210 in the match as West Indies, chasing 478 for victory, were all out for 267.

Shivnarine Chanderpaul, 128 not out in the first innings, was 97 not out.

England captain, Michael Vaughan, praised Giles' performance and the English batting during the first innings which set the platform for the win.

"The way we batted in the first innings set up the victory," said Vaughan. "Ashley Giles proved what a fantastic bowler he is."

West Indian captain, Brian Lara, admitted that the match escaped them after England's first innings of 568.

"Chasing 391 runs on the first day, was asking for trouble," Lara said.

However Lara defended his decision to put England into bat.

"We noticed that teams which batted first had been put under a lot of pressure."

West Indies resumed after lunch on 195 for six, needing a further 283 to win with Chanderpaul 39 not out and Omari Banks nought not out.

Banks, however, never got off the mark, fast bowler Stephen Harmison knocking over his off-stump to leave West Indies 200 for seven.

And eight balls later Tino Best (three) charged down the pitch against left-arm spinner Giles and was easily stumped by wicketkeeper Geraint Jones.

Left-hander Chanderpaul then reached a gutsy fifty off 91 balls with eight fours as rain closed in.

Chanderpaul, on 69, then missed an intended pull off fast bowler Simon Jones and collapsed after the ball hit him on the inside of his right knee.

Pedro Collins hung around gamely for nearly an hour, before he was stumped by Jones for two to give Giles his fifth wicket.

And with Chanderpaul in sight of a century, last man Fidel Edwards was caught behind off all-rounder Andrew Flintoff.

Chanderpaul batted for 230 minutes facing 152 balls with 18 fours.

In Monday's first session, Giles struck twice, the prize dismissal of Lara his 100th Test wicket, to spark a spell that saw the tourists lose three wickets for 23 runs.

Giles bowled his former Warwickshire team-mate Lara for 44 with a superb delivery that spun sharply out of the rough to give the 31-year-old bowler his 100th Test wicket in his 37th match.

The skipper's exit left West Indies 172 for four.

None of left-hander Lara's 26 Test hundreds had been made at Lord's and at the age of 35 he was unlikely to get another chance.

Giles then dismissed Test debutant Dwayne Bravo (10) after the 20-year-old chipped back a simple return catch as the bowler followed up his first innings return of four for 129, which also included Lara, in style.
