Sterling hit its highest level since the 2008 financial crisis on Tuesday after a survey showed British manufacturing growing at its fastest in seven months, adding to the case for a rise in interest rates this year.

The PMI index of sentiment among manufacturing purchasing managers rose to 57.5 in June from 57.0 in May - its highest since November and well above the 50 line that divides growth from contraction. Economists in a Reuters poll had expected the index to fall to 56.8.
