Only a week before, it was reported that Mr Howard had been planning to use an early opportunity to call for renegotiation of Britain's position in Europe. By going public first, Mr Dorrell succeeded in outflanking the Home Secretary.
Any doubt that a leadership contest is already under way should be dispelled by Mr Howard's diary for 1996 - he spoke at more constituency association lunches and dinners than any other cabinet minister in the past three months. Central Office said his work rate with the constituencies had almost doubled. Some Tory MPs are already informally working for his election as leader.
Mr Howard was responsible for bringing to a head the internal tensions in the Cabinet on Europe at two highly charged cabinet meetings last month. The Home Secretary ambushed Kenneth Clarke at a cabinet meeting on 5 December with a demand that the Chancellor should produce a paper on the convergence criteria for the single European currency.
There were briefings by "friends" of Mr Howard, which clearly showed that he was the man to stand up to Mr Clarke. However, Mr Clarke then pulled a trick on the Cabinet. Ministers had been expecting a paper in the new year but the Chancellor delivered it at a meeting on 19 December.
His paper was torn to shreds by his colleagues and the Chancellor was ordered to return with a fresh paper in the new year. The significant factor was the number of ministers who now sided with Mr Howard. Mr Dorrell was among them. Others who chipped in included Gillian Shephard, the Secretary of State for Education.
Mr Clarke was able to claim a victory, because the Cabinet agreed to stick to the existing policy on Europe, but the impression was of a chancellor at bay. The intervention by Mr Dorrell was seen as an attempt by John Major to force Mr Clarke to move from the existing "wait and see" approach to a single currency, which the Euro-sceptics said yesterday was "untenable" for the election.
It will not be the first time Mr Major has used Mr Dorrell as his stalking horse. Last summer, Mr Dorrell called for a referendum on Europe when it was being resisted by the Chancellor. Within a few weeks, Mr Major had persuaded Mr Clarke to accept it. By using Mr Dorrell, the Prime Minister could engineer a change of policy without risking a direct conflict between himself and his Chancellor.
The difficulty for Mr Major is to reach an agreed policy without forcing resignations from the pro-Clarke wing of the Tory party. The greatest fear among the Euro-sceptics is that they will be blamed for an election defeat.
Michael Portillo, the Secretary of State for Defence called for "unity, unity, unity" at the 1996 party conference. The aim was to close cabinet ranks against the former minister Mr Redwood and backbench Euro-sceptics who were putting their principles above the party's election chances. Mr Redwood has since gone relatively quiet.
But the ground is moving under the Chancellor who is becoming more isolated in the Cabinet. Michael Heseltine, the Deputy Prime Minister, has stood by the Chancellor, but also has his own eye on the leadership election. Mr Major is likely to call his next-door neighbour for a chat soon, to discuss the idea raised by Mr Dorrell.
Profile: Aged 44, Secretary of State for Health. Dripping wet but drying out fast.
Campaign strategy: Meets backbenchers for quiet chat in his rooms; bidding for centre-right ground with former Clarke votes in the bag. Carefully timed briefing by "friends" to Daily Telegraph - noticeboard of the Euro-sceptics.

Odds - 6:1
Profile: Aged 55, Home Secretary - right-winger; impeccable Euro-sceptic, with long-term hostility to federal Europe.
