(ShareCast News) - The FTSE 250 continued to drop on Thursday, with the market down 52.17 points (0.30%) to 17,087.68 by mid-afternoon.Political events in South Arica caused Investec to plummet throughout the day. President Jacob Zuma on Wednesday evening fired the country's finance minister, Nhlanhla Nene - a decision that weighed on financial assets from the country. Nene was replaced by David van Rooyen, whom some reports described a little-known backbencher with no previous experience in finance.One report linked Nene's defenestration to his ministry's opposition to the president's plans for an approximately $100bn deal to purchase eight nuclear reactors from the Russian Federation and question marks surrounding deals at state-owned airline SAA. The unexpected decision sent Investec shares plummeting as well as the South African rand sharply dropping versus the US dollar.Different issues in a different part of the continent created problems for PZ Cussons. The personal care and beauty products maker maintained a flat performance in the first six months of its financial year but warned that risks remained about its key market of Nigeria.It confirmed profits were "broadly flat" compared to the same period last year as a strong performance in the UK balanced a Nigerian market where the oil price slump has hit consumer disposable incomes. While Nigerian demand for personal and home care remained solid, and are expected to continue so, the lack of disposable income hit the local Haier Thermocool electricals business, which makes refrigerators, freezers and washing machines. If there is no improvement in the Nigerian economy, the electricals performance in the seasonally important second half is expected to be "significantly lower".Online grocer Ocado reported double-digit sales growth in a "challenging and competitive" grocery retail environment.

The group sales figures represented a slowdown from last year but were still a touch above analysts' forecasts.

However analysts at Investec said the key attraction of the shares lay in its ability to return high volumes of cash in the medium-term. Sales at the server software provider declined by 2%, which was ahead of guidance for a drop of between 2% and 4%, while operating costs fell from $382.5m to $340.6m, the broker explained.
