Ocado tumbled as the online grocery and warehouse tech group's full-year results failed to impress, while Trustpilot also fell sharply after a trading update.

Engineering firm Rotork rocketed after it agreed to be bought by Swiss engineering company ABB in a £4.1bn deal.

Dunelm also rose after the homeware retailer said full-year profit was set to be in line with its guidance and consensus, as it reported an increase in fourth-quarter sales.
