The not-for-profit research consultancy’s latest Charity Parliamentary Monitor polled 97 members of the House of Lords.
It found that although 79 per cent say letters, emails and faxes are their main form of contact with charities, they rank them as only the second-most influential.
Parliamentary receptions were viewed as the third-most influential, with party conference fringe meetings coming in fourth. Other methods of direct contact included parliamentary receptions (68 per cent), briefings or face-to-face meetings at Westminster (48 per cent) and party conference fringe meetings (28 per cent).
The Guardian emerged as the most popular weekly newspaper, with 59 per cent of peers claiming to be regular readers.
