Pritchard has said the allegations are false and he is consulting his lawyers.
In an undercover investigation by the newspaper, a journalist posed as a foreign businessman and approached Pritchard while he was travelling in Malta.
The Telegraph has published claims that Pritchard suggested the reporter should invest £10m in a group of boutique hotels in Albania and that he asked to be paid £3,000 a month for his consultancy services as well as 3 per cent of any deal.
Pritchard stressed he would not lobby on behalf of clients, according to the newspaper.
