LTIP and Capital Gains

I received share from an LTIP in April this year, on vesting my employer sold some of the shares to pay tax and NI, which is shown on my payslip and the remainder of the shares were transferred to an equiniti global nominee account. If i now sell those shares do i need to pay CGT on them ?

Hi 

Please refer to guidance here Securities disposed of for more than their market value

Thank you
