(Sharecast News) - London's FTSE 100 was down 0.6% at 10,378.47 in afternoon trade on Tuesday.

Miniature wargames manufacturer Games Workshop was the standout gainer on the index.

Shares in Scottish Mortgage Investment Trust rallied after Reuters reported that SpaceX - in which it has a significant holding - is preparing to launch its initial public offering roadshow in early June as it moves closer to what could become the largest IPO on record.

The Elon Musk-led rocket and space technology company reportedly told its banking syndicate that it plans to raise around $75bn, implying a valuation of up to $1.75trn. The roadshow was expected to begin in the week of 8 June, with roughly 125 analysts from 21 participating banks scheduled to meet management ahead of the investor presentations.

According to Reuters, a defining feature of the offering would be an unusually large allocation of shares to retail investors.

Metlen Energy & Metals was also in the black ahead of full-year results on Thursday.

On the downside, defence firms and pharmaceuticals fell, with Rolls-Royce, Melrose, Babcock, BAE Systems, AstraZeneca and GSK all weaker.
