(Sharecast News) - London's FTSE 250 was 2% higher at 21,320.40 in afternoon trade on Friday.

Drax rallied after saying that full-year adjusted EBITDA was set to be at the "top end" of analysts' consensus estimates of £881m to £996m following a strong performance in the first half.

Babcock International gained after it posted a jump in full-year profit as it continued to be boosted by a "sustained uplift" in global defence budgets, with a strong performance in Nuclear, Land and Aviation.

In the 12 months to the end of March, underlying operating profit rose 34% from a year earlier to £238m, with revenue nudging down to £4.39bn from £4.44bn.

Babcock said the contract backlog grew 9% to £10.3bn, driven by Nuclear and Marine.

Computacenter lost ground as it said it was expecting to report a decline in first-half profit due to the delay of the fulfilment of some orders in North America, but also announced a £200m share buyback programme.
