England's Katy Mclean brushes past France centre Sandrine Ramkilaoun
England Women maintained their unbeaten record in the 2011 Six Nations with a hard-fought win over France at Worcester's Sixways Stadium.
Tries for hooker Amy Garnett and skipper Katy McLean sealed the victory but England had to be patient with both scores coming in the last 20 minutes.
"We lacked precision at times but the important thing is we are still on track," said England coach Gary Street.
England remain on course to clinch a sixth consecutive Grand Slam.
The reigning champions controlled much of the game, but Street was disappointed that they struggled to turn possession into points.
"We were very sporadic today and we managed to squander quite a few opportunities," he added. "It was frustrating because we got ourselves into some good positions but we missed the try scoring opportunities.
"There's lots for us to work on but we have now got a good focus for our game against Scotland. We know where the improvements need to be made."
McLean ensured England got off to a great start, catching France cold with a strong break. But the visitors crowded England out and averted the danger.
However, it was the visitiors who took the lead in the 26th minute through a penalty from fly-half Nadge Casenave, who took over kicking duties from Sandrine Agricole after the latter's earlier miss.

McLean then levelled the score with a successful penalty right on the stroke of half-time, before putting England ahead with another in the 49th minute.
With the home side only three points ahead at 6-3, they made a number of changes with Amy Garnett, Rachael Burford and Catherine Spence all coming on.
Burford almost made an instant impression, coming close to driving over the try-line, but France's defence held firm.
However, England were not be denied a few minutes later when Garnett picked up from the back of a ruck and barged her way over the line. McLean missed the penalty but England led 11-3 after 72 minutes.
McLean then rounded off the win in injury time when Street's side fed the ball out to the right wing as McLean found space to score the final try.
She missed the resulting conversion, but the points secured an important win for England, who play Scotland at Twickenham on March 13.
