Computacenter was a high riser after beating off competition for a Foreign & Commonwealth Office (FCO) contract. The group said the deal carries a value of between £65m and £350m over a period of six years. CSR, which provides multifunction connectivity, audio and location platforms, was another strong riser, regaining some of Friday's losses. ICAP is in talks about a settlement over its role in the Libor rate-rigging scandal which could see it pay about £70m ($109m) to British and US regulators, Sky News reported. Meanwhile, inkjet printhead supplier Xaar was the big faller of the day. Ten days ago the company posted impressive half-year results, with one broker going so far as to call them "spectacular". Imagination Technologies was also lower a few days after launching Caskeid, which it described as "the world's most accurately synchronised wireless multiroom connected audio streaming technology".
