I still think I am the best spinning option in the country Ashley Giles More reaction

Ashley Giles cemented England's strong position in the first Test against West Indies after Rob Key and Michael Vaughan filled their boots at Lord's.

After dismissing England for 568, West Indies reached 208-4 at stumps with spinner Giles returning 3-58.

Captain Vaughan made 103 to supplement Key's 221 - his highest first-class score - but England lost their last seven wickets for 41 runs.

Left-armer Pedro Collins (4-114) was the architect of the collapse.

Chris Gayle and Devon Smith looked determined to make England pay with a fiery opening stand of 118, but Giles engineered another collapse that saw four Windies wickets fall for 21.

The visitors, still 161 runs short of the follow-on mark, were held together until the close by not-out batsmen Shivnarine Chanderpaul (41) and Dwayne Bravo (30).

Although England scored freely in the opening hour of play, adding 79 unbroken runs, Collins asked numerous questions of Key with balls angled across the right-hander.

Key and Vaughan put on 165 together for the third wicket

As on Thursday, Key played and missed several times but punished the bad balls, reaching his maiden first-class double century with his 29th boundary.

England were rolling towards a score in the region of 700 as their third wicket took them to within 15 runs of 500.

But a loose Key cut that picked out Brian Lara at point signalled the end of England's dominance.

The only cheer for England after Key's dismissal was Vaughan's continuing good form which resulted in his 12th Test century.

Indeed, his team-mates were dropping at such a frequency that it seemed the England captain could be left stranded in double-figures.

The falling of Graham Thorpe, caught behind chasing Bravo (3-74) wide outside off, sparked the interminable slide.

Andrew Flintoff, ruled fit to bowl after all by medics, was bowled by Omari banks on the stroke of tea, and the rest followed for single figures after the break as Collins wrapped up the tail.

Lara copped a terrible decision to be given out caught behind

It was a soft end to what had been a hard-nosed effort by England, and the collapse looked certain to plague England as the Windies reply got off to an electric start.

Smith was little more than a spectator in the opening 10 overs as Gayle's 44-ball half-century sped the visitors to 73-0.

Lara baited England prior to the match with talk of England's attack being over-reliant on Steve Harmison, and Gayle blasted the paceman out of the attack after four overs, one of them going for four boundaries.

The runs flowed after tea as a new first-wicket record for the Windies at Lord's was set, but, in the form of Giles, England's Plan B was soon to take centre stage.

The follow on will be available for Vaughan to enforce - whether or not he does is another matter From West Indian Ninja Have your say on TMS

West Indies suddenly slumped from 118-0 to 139-4, with Giles removing Smith (bowled for 45), Gayle (lbw for 65) and Lara (caught behind for 11) in the space of 27 balls.

Both Gayle and Lara were victims of poor umpiring decisions, but with Matthew Hoggard also trapping Ramnaresh Sarwan lbw for one the Windies were nevertheless on the ropes.

No more wickets fell as the fifth wicket stood firm, but surely Giles, again answering critics who felt England should have played four pacemen, will have more to say on day three.
