Shares in Minerva rose by almost a quarter on Thursday after Limitless, a unit of sovereign wealth fund Dubai World, said it was mulling a takeover offer for the British property developer.

In a statement, Limitless said it had not made a formal approach to Minerva's board and that it was in the 'very preliminary stages of considering its options'.

Shares in Minerva were up more than 23 percent at 124 pence by 1111 GMT as investors hoped to benefit from signs of emerging foreign investor interest in central London's battered real estate market.

'I was in the Middle East last week talking to a lot of investors in Dubai, Abu Dhabi, and Qatar and the location they all kept asking about was London,' Tony Horrell, head of European capital markets at property services firm Jones Lang LaSalle told Reuters late on Wednesday.

'And the reason being because they regard it as a world city and when they think about the UK they think of London. So that money which is lowly geared is focused on the core end,' he said.

Minerva owns two development schemes in London's City financial district and is building a major shopping centre in Croydon, on the southern tip of greater London.

Commercial property prices in the UK have fallen sharply since the start of the global credit crunch compared with other real estate markets. Valuations on average have been slashed by 16 percent since the summer and anecdotal evidence suggests asking prices could be up to 10 percent lower still.
