- Chemring's revenues increased to £156.7m in the four months from 1 may to the end of August - 13.4% up on the corresponding period last year.

The group said trading in the period had progressed as planned and the board's current expectations for the year ending 31 October remained unchanged.

It said the order book at 31 August was £541.8 million, 2.6% lower than the order book of £556.2 million at 30 April.

But it added: "Recent orders received, for delivery in FY18, give us increased confidence in the Group's prospects in the near term."
