An end-of-year report shows that Oxford East's Andrew Smith has been the most active of Oxfordshire's MPs in using his vote in Parliament.

The former Cabinet minister voted in 68 per cent of the "divisions" held during the 2003/4 Parliamentary session, when the average record out of all 659 MPs was 65 per cent.

Witney's Conservative MP, David Cameron, voted on 65 per cent of occasions, but the rest of Oxfordshire's representatives in Westminster were below average.

Tony Baldry, MP for Banbury, scored 51 per cent, Wantage's Robert Jackson 47 per cent, Oxford West and Abingdon's Evan Harris 45 per cent and Henley's Boris Johnson 44 per cent.

But the authors of the report, which has been placed in the House of Commons Library, warned that there were different factors to be taken into account concerning voting records.

"Participation may be affected by a number of factors," Ross Young and Jeremy Hardacre said in the foreword.

"These may include Ministerial or Opposition frontbench duties, visits abroad as part of a Parliamentary or Committee delegation, constituency business or party duties."

Prime Minister Tony Blair voted in just six per cent of divisions and the Chancellor, Gordon Brown, eight per cent.

In Oxfordshire, Mr Smith was Work and Pensions Secretary until his resignation in September, Mr Johnson spent six months as the Tories' arts spokesman until he was fired last month, and Liberal Democrat Dr Harris is a member of the Science and Technology Committee.

Tory Mr Jackson is a member of the Defence Committee, Mr Baldry is the Conservative chairman of the International Development Committee and Mr Cameron is deputy chairman of the Conservative Party.

Other factors include Parliamentary trips abroad, sickness and constituency business. There is no record, either, of MPs' abstentions even when they are present.

Mr Smith said yesterday: "I'm pleased my Commons voting record was the best in Oxfordshire."

But he stressed: "Voting is only one aspect of the work MPs do."
