Brit Insurance is using retained financial PR firm Haggie Financial. Patern Peter Rigby is leading the account.
Last week Brit Insurance rejected a takeover proposal from Apollo worth £824m, but said it would be willing to do a deal at the right price.
Weekend reports said Apollo had told Brit it would not make any further offers without preliminary access to the company’s books.
FD in London advises Apollo in relation to the firm's Euronext-listed private equity fund, AP Alternative Assets (AAA). However, FD is not thought to be involved in the Brit Insurance bid.
Brit operates in the Lloyd's of London LOL.UL insurance market and acts as an insurer to small and medium-sized businesses.
