It is a stressful period for Tony Blair, now that transit Uranus is conjunct his progressed Midheaven and transit Pluto is inconjunct his natal Ascendant. Those are two different difficulties, reflecting two different things.
First: there is a lot of fuss about the ways that the former socialist MP earns his millions. Uranus is in the 3rd Placidus house of communications (he is mostly doing speeches for about 2.000 pounds per minute) and in the 2nd equal house (of money).
Second: transit Pluto, inconjunct the natal Ascendant, is in line with the investigations about the Iraq war. Uranus and Pluto are the symbols of tension related to upheavel, news, incidents, inqueries and (political) problems.
The fact that transit Uranus AND transit Pluto are making an aspect with the natal and progressed chart tells us, that it won't be easy for him to have to face the Chilcot Committee. However, transit Saturn is trine his natal Ascendant. And transit Jupiter will soon be making a square. Maybe it is tense, but Tony Blair is a 'die hard' and he will be supported by the best lawyers money can buy.
