Capital gains tax in UK if overseas capital gains is reinvested to receive an exemption

Hi, I am a UK resident and a UK citizen by naturalization. I am looking to sell a property that I own in India . I plan to reinvest the capital gains in India itself in Indian central government bonds and there by receive an exemption from capital gains tax according to Indian tax rules - "Section 54EC: Exemption from the Sale of Real Estate When Reinvesting in Specific Bonds". Two Questions : a) In the above situation, should i declare the sale and proceeds to HMRC while I file my tax returns in the UK and b) If so, will I incur capital gains tax in the UK even though I reinvest the capital gains back in india in specific bonds and get tax relief in india? Appreciate your response. Thank you
