On the LSE there are 'order-driven' stocks and 'quote-driven' stocks. The order-driven ones do indeed get affected by algorithmic trades but RBW is quote driven and the electronic bids and offers are controlled by human market makers and as I said, are a reflection of the current supply/demand dynamic.
Under the quote-driven system (on which RBW trades), market makers are obliged by the LSE to quote in a size determined by recent turnover, shares in issue etc to try to ensure continuous liquidity.
