British manufacturing grew at its fastest rate in more than two years at the start of the third quarter and looks set to help the recovering economy gain momentum, a survey showed on Thursday.
The Markit/CIPS Manufacturing Purchasing Managers' Index (PMI) jumped to 54.6 in July from an upwardly revised 52.9 in June, its fourth straight month of expansion.
The reading was the strongest since March 2011 and beat by a wide margin even the most optimistic forecast in a Reuters poll of economists.

The latest sign that Britain's economy is edging closer to sustainable growth - termed "escape velocity" by the Bank of England's new governor Mark Carney - will feed into Thursday's discussions at the central bank, which is due to announce its policy decision at 1100 GMT.
Whether it proves lasting or not, British economic growth is accelerating, with the International Monetary Fund predicting a 0.9 percent rise in gross domestic product this year, up from a limp 0.2 percent in 2012.
