Neil Woodford, who controversially locked investors into his Equity Income fund, has sold his 20% stake in ultrasound haptic touch specialist Ultrahaptics.

Woodford invested in Ultrahaptics’ £10.1 million Series A funding round in 2015.

It is being reported that he sold his stake for £20 million.

Last year Ultrahaptics raised £35 million in a funding round which valued Ultrahaptics at £150 million.

Woodford is reported to have raised £800 million in sales of stakes in companies in a bid to raise funds.

Investors in the Equity Income fund have been protesting at being stopped from liquidating their holdings.

Woodford’s Equity Income fund also owns stakes in Oxford Nanopore and BenevolenAI.
